2 Tricks for Remembering Greater Than and Less Than Signs

2 Tricks for Remembering Greater Than and Less Than Signs SAT / ACT Prep Online Guides and Tips What do those little sideways carat symbols mean? They're inequalities! Inequalities can be difficult to get a handle on, especially because the greater than and less than signs look so similar. But these symbols are very useful, because they help us show the relationship between numbers or equations in a way that doesn't just say that they're equal. In this article, we’ll be talking about what inequalities are, how they’re represented, and how to remember which sign means what. Not knowing what the signs mean may make your math homework feel something like this. What Are Greater Than and Less Than Signs For? Inequalities are math problems that don’t resolve with a clear â€Å"equals† answer- instead, they compare two things, demonstrating the relationship between them rather than showing that one is equal to another. Hence the name; â€Å"inequality† means that two things are not equal. We’re all familiar with the equal sign, â€Å"=† at this point in math. But â€Å"† and â€Å"† are not as common, let alone â€Å"≠¥Ã¢â‚¬  and â€Å"≠¤Ã¢â‚¬ . Here’s a chart to cover all the inequality symbols: Symbol Meaning Less than- the number on the left is less than the number on the right; 2 3 Greater than- the number on the left is greater than the number on the right; 3 2 ≠¤ Less than or equal to- the number on the left is less than or equal to the number on the right; 2 or 3 ≠¤ 3 ≠¥ Greater than or equal to- the number on the left is greater than or equal to the number on the right; 2 or 3 ≠¥ 2 ≠  Does not equal- the number on the left does not equal the number on the right; 2 ≠  3 Now we'll finally get to talk about why all these photos are of crocodiles. How to Remember Greater Than and Less Than Signs Though the greater than and less than signs have clear meanings, they can be kind of hard to remember. All of them look similar, with the exception of the â€Å"does not equal† sign. So how can you remember them? Alligator Method One of the best ways to memorize the greater than and less than signs is to imagine them as little alligators (or crocodiles), with the numbers on either side representing a number of fish. The alligator always wants to eat the larger number of fish, so whatever number the mouth is open toward is the larger number. The alligator’s mouth is open toward the 4, so even if we weren’t sure that 4 is a bigger number than 3, the sign would tell us. All inequality signs give us the relationship between the first number and the second, beginning with the first number, so 4 3 translates to â€Å"4 is greater than 3.† This also works the other way around. If you see 5 8, imagine the sign as a little alligator mouth about to chomp down on some fish. The mouth is pointed at the 8, which means that 8 is more than 5. The sign always tells us the relationship between the first number and the second, so 5 8 can be translated to â€Å"5 is less than 8.† When you’re working with inequalities, you can even draw little eyes on the symbols to help you remember which means which. These can be tricky to remember, so don’t be afraid to get a little creative until you really have them memorized! Rotateyour less than sign a little bit and you get an L for "less than!" L Method This method is pretty simple- †less than† starts with a letter L, so the symbol that looks most like an L is the one that means â€Å"less than.† looks more like an L than , so means â€Å"less than.† Because doesn’t look like an L, it can’t be â€Å"less than.† Equal Sign Method Once you’ve mastered the Alligator or L method, the other symbols are easy! â€Å"Greater than or equal to† and â€Å"less than or equal to† are just the applicable symbol with half an equal sign under it. For example, 4 or 3 ≠¥ 1 shows us a greater sign over half an equal sign, meaning that 4 or 3 are greater than or equal to 1. It works the other way, too. 1 ≠¤ 2 or 3 shows us a less than sign over half of an equal sign, so we know it means that 1 is less than or equal to 2 or 3. The â€Å"does not equal† sign is even easier! It’s just an equal sign crossed out. If you see an equal sign crossed out, it means that the equal sign doesn’t apply- thus, 2 ≠  3 means that 2 does not equal 3. Keep these things in mind and you'll look this happy about working with inequalities. Key Tips For Working With Inequalities Inequalities are tricky- we’re used to having a clear and concrete answer for math problems, butinequalities don't always give us that. When you're working with inequalities, keep these things in mind to help ease you through the process. Inequalities are All About Relationships Keep in mind as you’re working on inequalities that they’re typically asking you to solve for a relationship or to identify which symbol is appropriate rather than asking you to solve for a single number. You don’t need to end up with two numbers on either side of an equal sign to be right- the answer just needs to be true. Isolate Your Variables When you’re working with inequalities with variables, it’s important to remember that, in general, you’ll be trying to isolate the variable to one side or the other. Focus on condensing numbers and canceling things out when you can, always with the goal of getting the variable alone on either side of the equation. Negative Numbers Change the Greater Than or Less Than Sign Don’t forget that performing certain actions will flip the sign. When you multiply or divide by a negative number, you need to flip the â€Å"greater than† or â€Å"less than† sign along with it. Don't Multiply or Divide by a Variable- Most of the Time Unless you know for certain that a variable will always be positive or always be negative, don’t multiply or divide an inequality by a variable. What’s Next? Inequalities aren't the only tricky part of math- rational numbers can also be confusing! This guide will help walk you through what a rational number is and what they look like.

Discover the Worlds Smallest Tree

Discover the World's Smallest Tree Some people claim that the title Worlds Smallest Tree should go to a tiny plant that grows in the coldest regions of the Northern Hemisphere. Salix herbacea, or dwarf willow, is described by some Internet sources as the very smallest tree in the world. Others see the tree as a woody shrub that does not meet the definition of a tree accepted by botanists and foresters. Definition of a Tree The definition of a tree that most tree scholars recognize is a woody plant with a single erect perennial trunk that reaches at least 3 inches in diameter at breast height (DBH)Â  when mature. That certainly does not fit the dwarf willow, although the plant is a willow family member. Dwarf Willow Dwarf Willow or Salix herbacea is one of the smallest woody plants in the world. It typically grows to only 1-6 cm in height and has round, shiny green leaves 1-2 cm long and broad. Like all members of genus Salix, dwarf willow has both male and female catkins but on separate plants. The female catkins are red in color, while the male catkins are yellow.

Overcoming My Anxiety in Public Speaking Essay Example | Topics and Well Written Essays - 500 words

Overcoming My Anxiety in Public Speaking - Essay Example As expected in my profession, I am required to present the children’s condition including the approach and methodology applied in Individualized Education Program (IEP) meetings. Armed with my evaluation papers and a few bulleted note cards outlining my whole presentation—which I rehearsed over and over until the last minute—I still felt as if a full bucket of nervousness was drenching my whole body. The situation catapulted me to my primary and secondary years and once again I am again a high school student before the analytical eye of my professor and the mocking glare of my classmates; as if every eye is staring at the flaws in my face, counting every drop of sweat, listening to the quivering of my voice, watching the trembling of my hands, and making a mental note of every mistake that would come out of my mouth. But I had to shake off the imaginary time warp and forced myself to get a rock-hard grip on the present. I strived to produce a genuine smile as I a cknowledged the audience and proceeded to my presentation. The discussion went pretty well although there were few verbal lapses which I believe is forgivable enough. It’s a total relief that it’s over and done with. There will be succeeding occasions when I would have to speak again but I know that it wouldn’t be as hard as it had in the previous times. I may not be the best speaker and not everyone may appreciate my speech but never again will I dread the opportunity to impart the knowledge which I believe is of benefit to the listeners.

Short answers - Coursework Example Any archeologist will say that an artifact’s context is as important as its characteristics for revealing information about the past. The importance of context may extend to a research setting whereby archeologists work. Awareness of the context enables public archeologists to recognize the impacts their research have on the communities within which they work, to include community members in the research as equal participants where they can and if opportunity arise and to actively engage in social change through the research (Stottman 141). At this stage of evolution, man was walking on all fours and had chimpanzee like body features. It is funny because there is a man in the photo who can walk with the legs only without using his hands. The other men are shocked and he is laughing at them but they are not amused. The gracile specimens from Olduvai George are Homo habillis but there are some provisos (Robinson, David & Ash). Their spinal cords’ opening is near the middle of the skull. The skull base is small but its width is bigger. Their faces are small in width and their nasal openings are sharply defined. Moreover, their post canine teeth are small. They had flat noses and projecting lower jaws that made them to look like apes. They had small brains, strong arms, curved fingers, small canine teeth, stood on two legs and walked upright (Robinson, David & Ash). Jane Goodall is a British anthropologist and primatologist presently celebrated for his immense contribution in research regarding chimps. This is especially in terms of their interactions and relations in terms on family structure carried out in

Developing Professional Practice - Assignment Example The functions of such professionals include working with people towards continuous compliance with legal, ethical, and professional standards (Bowman, Jonathan, and Montgomery 4-6). The Human resource Advisory role includes offering services in transforming, changing, and improving the organization. At Vodafone Qatar, professional standards of human resource practitioners is key to success. The human resource profession assists an organization in the selection, compensation and in offering advice related to human performance within the organization. Human resource professionals assist organizations in the planning, motivating, compensating and in organizing human resources as factors of production. Human resource professionals with an advisory role in the organization need to be conversant with their professional standards. Qatar Vodafone wishes to use innovative research in promoting professional as well as professional development. It is prudent for one to understand those codes of conduct, corporate social responsibilities, and ethics (Jackson 13). These aspects are essential in organizations in ensuring that there is uniformity. Maintenance of such standards ensures a professional outlook to the human resource professional body. Professionalism of such advisors assists organizations cut on cost. Professional human resource practitioners, on the other hand, should understand their ethical, professional obligations. They also need to be creative in motivating members of staff; this may be in the form of incentive provision and in ensuring that workforce work under safe and conducive environment. Human resource professionals need to be sensitive on their code of conduct (Koonmee 20-23). This means that such professionals need to understand their mandate and their positions in such organization. In relation to the code of conduct, a human resource

Causes effects and history of prostitution

Causes effects and history of prostitution Prostitution is listed among the crimes some refer to as victimless or consensual crimes, but research shows that may not be the true picture of prostitution. Before proceeding, we need to define prostitution. Despite of the fact that, prostitution being known as the oldest profession in the history of mankind. The workable definition has proven elusive. From a dictionary we learn that prostitution is the act or practice of engaging in sexual intercourse for money. But a prostitute cannot simply be a woman who sells her body, since that was the norm of the society that women will get marriage in order to accomplish home and better life style. Promiscuity has been proposed as another candidate. Medieval canon lawyer Johannes Teutonicus suggested that a woman who had sex with more than 23,000 men should be classified as a prostitute, although, furthermore he says that sexual intercourse with 40 to 60 opposite gender would also be called prostitute. However, promiscuity itself does not turn a woman into a prostitute. Although a vast majority of prostitutes are promiscuous, most people would agree that sleeping around does not amount to prostitution. Hence I define prostitution as systematic sexual violence and oppression against female. Selected national and international research projects and various programs by women have been initiated to address the health burden of violence against women. Such projects have especially focused on the health consequences to women of battering or domestic violence, rape and sexual assault, child sexual abuse and incest, and female genital mutilation (See, for example, World Bank Discussion Papers 255, Violence Against Women: the Hidden Health Burden). In depicting the health effects of such forms of violence against women, these projects attempt to make the violence, harm and human rights violation to women visible. However, a consideration of the dire health consequences of prostitution demonstrates that prostitution not only gravely impairs womens health but it is obviously violence against women. The health consequences to women from prostitution are the same injuries and infections suffered by women who are subjected to other forms of violence. The physical health consequences include: injury (bruises, broken bones, black eyes, concussions). A 1994 study conducted with 68 women in Minneapolis/St.Paul who had been prostituted for at least six months found that 50% of those women had been physically assaulted by their purchasers, and a third of those experienced purchaser assaults at least several times a year. 23% of those assaulted were beaten severely enough to have broken bones. Furthermore, 90% of the women in this study had experienced violence in their personal relationships resulting in miscarriage, stabbing, loss of consciousness, and head injuries (Parriott, Health Experiences of Twin Cities Women Used in Prostitution). Prostitution is physically harmful to women. STDs (including HIV/AIDS, chlamydia, gonorrhea, herpes, human papilloma virus, and syphilis) are alarmingly high among women in prostitution. Only 15 % of the women in the Minneapolis/St. Paul study had never contracted one of the STDs, not including AIDS, most injurious to health (chlamydia, syphilis, gonorrheal, herpes). General gynecological problems, but in particular chronic pelvic pain and pelvic inflammatory disease (PID), plague women in prostitution. The Minneapolis/St. Paul study reported that 31% of the women interviewed had experienced at least one episode of PID which accounts for most of the serious illness associated with STD infection. Among these women, there was also a high incidence of positive pap smears, several times greater than the Minnesota Department of Healths cervical cancer screening program for low and middle income women. More STD episodes can increase the risk of cervical cancer. Another physical effect of p rostitution is unwanted pregnancy and miscarriage. Other health effects include irritable bowel syndrome, as well as partial and permanent disability. The emotional health consequences of prostitution include severe trauma, stress, depression, anxiety, self-medication through alcohol and drug abuse; and eating disorders. Almost all the women in the Minneapolis/St. Paul study categorized themselves as chemically-addicted. Crack cocaine and alcohol were used most frequently. Ultimately, women in prostitution are also at special risk for self-mutilation, suicide and homicide. 46% of the women in the Minneapolis/St. Paul study had attempted suicide, and 19% had tried to harm themselves physically in different ways, for example, in another survey of 55 victims/survivors of prostitution who used the services of the Council for Prostitution Alternative in Portland, Oregon, 78% were victims of rape by pimps and male buyers an average of 49 times a year; 84% were the victims of aggravated as sault and were thus horribly beaten, often requiring emergency room attention and hospitalization; 53% were victims of sexual abuse and torture; and 27% were mutilated (Documentation available from the Council for Prostitution Alternatives). In developing countries, it has also been estimated that 70 percent of female infertility is caused by sexually transmitted diseases that can be traced back to their husbands or partners (Jodi L. Jacobson, The Other Epidemic, p. 10). Among women in rural Africa, female infertility is widespread from husbands or partners who migrate to urban areas, buy commercial sex, and bring home infection and sexually transmitted diseases. Women in prostitution industries have been blamed for this epidemic of STDs when in reality, studies confirm that it is men who buy sex in the process of migration who carry the disease from one prostitute woman to another and ultimately back to their wives and girlfriends. The movement of abandoned or rejected barren women to urban prostitution has been documented in Niger, Uganda, and the Central African Republic. Numerous studies in Africa and Asia by the World Bank and a number of international research organizations have found that divorced or separated wom en comprise the great majority of prostitutes or semi prostitutes (Jacobson, p. 13). Thus, a major health effect of the mass male consumption of commercial sex and the expansion of sex industries in developing countries is not only a rampant increase in sexually transmitted diseases but an exponential increase in infertility. The further effects of this vicious cycle insure that a whole new segment of women who are abandoned by their husbands due to infertility, are propelled into prostitution for survival. In both developing and industrialized country contexts, current campaigns to control the spread of HIV/AIDS by advocating safe sex for women in prostitution fail to address the blatant inequities between women who are bought for sex and the men who pay for it. Any AIDS strategy based on negotiating condom use between the purchaser of sex and the woman who must supply it assumes symmetry of power that does not even exist between women and men in many personal consensual relationsh ips. If AIDS programs are serious about eradicating AIDS, they must challenge the sex industry. Women in prostitution are targeted as the problem instead of making the sex industry problematic and challenging the mass male consumption of women and children in commercial sex. This is institutionalized when governments and NGOs argue for the medicalization of prostitution when they propose laws on prostitution which subject women to periodic medical check-ups. It is stated that women in the sex industry would be better protected if they submitted, or were required to submit, to health and especially STD screening. The way in which sex industries are responsible for the widespread health problems of women and children is mystified with proposals to implement health checks of women in the industry. No proposals have been forthcoming, from those who would propose both mandatory and voluntary medical surveillance for women in the sex industry, to medically monitor the men who would purchase sex. The same is true with current attempts to medicalize prostitution. No action will stabili ze the sex industry more than legitimating prostitution through the health care system. If medical personnel are called upon to monitor women in prostitution, as part of occupational health safety, we will have no hope of eradicating the industry. Furthermore, from a health perspective alone, it is inconceivable that medicalization of women in the industry will reduce infection and injury without concomitant medicalization of the male buyers. Thus medicalization, which is rightly viewed as a consumer protection act for men rather than as a real protection for women, ultimately protects neither women nor men. As with other forms of violence against women eradicating the health burden of prostitution entails addressing but going beyond its health effects. To address the health consequences of prostitution, the international human rights community must understand that prostitution harms women and that in addition to needing health services; women must be provided with the economic, social and psychological means to leave prostitution. Until prostitution is accepted as violence against women and a violation of womens human rights, the health consequences of prostitution cannot be addressed adequately. Conversely, until the health burden of prostitution is made visible, the violence of prostitution will remain hidden. Once Victor Hugo quotes stated in is novel; We say that slavery has vanished from European civilization, but this is not true. Slavery still exists, but now it applies only to women and its name is prostitution.

Behaviorism, Constructivism, and Cognitivism: Multiple Approaches To Le

A. Behaviorism, constructivism and cognitivism are relatively common theories used in the classroom as ways to approach student learning. Behaviorism focuses on observable behavior, such as students answering questions correctly, or being able to follow directions to complete a task as instructed. Characteristics of a classroom that uses behaviorism might be memorization of facts, writing vocabulary words, or a token reward system to inspire the desired behavior and decrease undesired behaviors. Constructivism, as indicated by the root word â€Å"construct,† focuses on the construction of new ideas, or expanding on what is already known. Students in a classroom using constructivism as a means for learning might seem more actively engaged in the learning process; they often learn something new through applying what they already know about the content area, and exploring new matter to further their understanding. This type of classroom often uses hands on manipulatives to allow students to actually build, create, or experiment with what they are learning. A cognitivism approach to learning might be explained by the minds capacity to process information – such as how a learner might remember something, retrieve information, or store new concepts. Learning through this method often depends on how the student processes what the teacher is presenting. Classrooms using this approach might incorporate learning strategies that help students categorize and sequence information to assist with processing. Like constructivism, it can be an active style of learning. A1. Support Personal examples of a behaviorist style of instruction are based on the widely renowned theory by B.F. Skinner, which in the classroom can be summarized by reinf... ...speaker and the listener. The student can store often used responses, and prepare anticipated answers prior to situations where he will be meeting with those less familiar with his speech capabilities. By implementing this type of device, the student has become more confident and can communicate appropriately for a student his age. In this instance, the integration of technology into the learning environment may make a difference as to whether the student is employable or overlooked due to the inability to communicate well on the job.
