The Difficulties Math Places on Students: A Summary of “Is Algebra Necessary?” In “Is Algebra Necessary?” by Andrew Hacker, an emeritus professor of political science at Queens College, City University of New York , Hacker critiques algebra, claiming that students are not passing, and that this is limiting the level of education available to them . Hacker suggests that if we make math more practical, by adding things such as “citizen statistics,” more students will succeed. In the beginning of his essay Hacker provides evidence many American students, from high school to college, are expected to fail their algebra classes. The author then makes the point that pressing students to take, and pass, math courses prevents some from discovering their own talents. Hacker suggests that algebra can cause students of all backgrounds to struggle, even when talented in other areas of academics. Hacker clarifies that the negative effects of math requirements occur in both high school and college level students, he makes this point by claiming that many universities expect a certain number of high school math courses for entrance, and require students to take math once in attendance. Hacker then argues that passing math alone is not good enough, claiming that many colleges look for high math SAT scores that are only achieved by a very small percentage of the population, making it difficult to be accepted into colleges. He then mentions that math in the classroom does not always apply to real world jobs, where much training is done specifically for the job after hiring. He then admits that people need basic math skills, but most workers will not need algebra or above. He further asserts that without math, the world as we know it would not exist, and that math is needed in this “statistical age.” Next Hacker clarifies that even when math is not related to a person’s field of study, it is sometimes still required to make a schools curriculum look impressive. Finally he...

12. When you flip a light switch, the light seems to come on almost immediately, giving the impression that the electrons in the wiring move very rapidly.
Part A: In reality, the individual electrons in a wire move very slowly through wires. A typical speed for an electron in a battery circuit is 5.0x10 to the -4th meters per second. How long does it take an electron moving at that speed to travel a wire 1.0 centimeter, or 1.0x10 to the -2nd?
Part B: Electrons move quickly through wires, but electric energy does. It moves at almost the speed of light, 3.0x10 to the 8th meters per second. How long would it take to travel 1.0 centimeters at the speed of light?
Part C: Electrons in an ordinary flashlight can travel a total distance of only several centimeters .suppose the distance an electron can travel in a flashlight circuit is 15 centimeters, or 1.5x10 to the -1st meter. The circumference of the earth is about 4.0x10 to the 7th meters. How many trips around the earth could a pulse of electric energy make at the speed of light in the same time an electron could travel through 15 centimeters of a battery circuit in 5.0x10 to the -4th meters per second?
For part A, the first step is to put (5.0) to the 10th to the -4th. The numerator would be (0.00050) if someone were trying to put 5.0x10 to the -4th in the form it’s supposed to be in. For the second scientific...

...Algebra is a way of working with numbers and signs to answer a mathematical problem (a question using numbers)
As a single word, "algebra" can mean[1]:
* Use of letters and symbols to represent values and their relations, especially for solving equations. This is also called "Elementary algebra". Historically, this was the meaning in pure mathematics too, like seen in "fundamental theorem of algebra", but not now.
* In modern pure mathematics,
* a major branch of mathematics which studies relations and operations. It's sometimes called abstract algebra, or "modern algebra" to distinguish it from elementary algebra.
* a mathematical structure as a "linear" ring, is also called "algebra," or sometimes "algebra over a field", to distinguish it from its generalizations.
A variable is a letter or symbol that takes place of a number in Algebra. Common symbols used are a, x, y, θ, and λ. The letters x and y are commonly used, but remember that any other symbols would work just as well.
Variables are used in algebra as placeholders for unknown numbers. If you see "3 + x", don't panic! All this means is that we are adding a number who's value we don't yet know.
Term: A term is a number or a variable or the product of a number and a variable(s).
An expression is two or more terms, with operations...

...Animal Kingdom
The animal kingdom is a taxonomic kingdom composed of multicellular, eukaryotic organisms. Mostly, their body structures become fixed as they develop, yet still some organisms in this kingdom have the ability to undergo metamorphosis. The majority of these organisms are motile, which means they can move on their own and with spontaneity. All animals are heterotrophic, which implies that they depend on other organisms for food. Animals live in places that provide their necessities to survive, called habitats. These basic necessities include food, water, protection from the environment, and appropriate space. In accordance with these necessities, there are a number of survival techniques used by organisms in this kingdom. These techniques can fall within the category of adaptations, which help these organisms adapt to various habitats. This kingdom falls in the domain Eukaryota, and there are nearly 40 different phyla that can be classified under the Kingdom Anamalia. Besides that there are 5 other lower levels in which these organisms can be classified, called class, order, family, genus and species. .
Invertebrates
Invertebrates are apart of the Animal Kingdom and are characterized by their inability to possess or develop a vertebral column. In the world of taxonomy, the word invertebrate is merely a convenient term used to help with this characterization. A great majority of the animal kingdom are invertebrates due to the fact that only 4% of animal...

When discussing parenting styles, the name of Diana Baumrind always comes up. She proposed the idea of different parenting styles based on how responsive and demanding a parent is. Three different parenting styles are compared and contrasted. Permissive parents are accepting and affirmative toward their child’s desires. Authoritarian parents try to completely control the behavior of their child while authoritative parents try to direct the child’s behavior in an orderly and structured manner. She then looks at eight different situations that have an effect on child behavior. Only findings that were 0.05 or lower there were concerned with disciplinary practices were published in the paper. These eight factors deal with the harmful side effects of punishment, the effectiveness of punishment, demands, and supervision. In the end, a discussion is proposed on how a balance is struck between control and freedom for the child (Baumrind, 1966).
In 1983, Maccoby and Martin expounded upon Baumrind’s parenting styles and even added a category of their own. They discovered that parenting styles can be discerned from how demanding and how responsive the parents are to their children. Demandingness refers to the expectations parents set up for their children in how they should act, while responsiveness refers to how well the parents interact with their children. Authoritative parents are high...

...Summary: Act I, scene i
Antonio, a Venetian merchant, complains to his friends, Salarino and Solanio, that a sadness has overtaken him and dulled his faculties, although he is at a loss to explain why. Salarino and Solanio suggest that his sadness must be due to his commercial investments, for Antonio has dispatched several trade ships to various ports. Salarino says it is impossible for Antonio not to feel sad at the thought of the perilous ocean sinking his entire investment, but Antonio assures his friends that his business ventures do not depend on the safe passage of any one ship. Solanio then declares that Antonio must be in love, but Antonio dismisses the suggestion.
The three men encounter Bassanio, Antonio’s kinsman, walking with two friends named Lorenzo and Gratiano. Salarino and Solanio bid Antonio farewell and depart. When Gratiano notices Antonio’s unhappiness and suggests that the merchant worries too much about business, Antonio responds that he is but a player on a stage, destined to play a sad part. Gratiano warns Antonio against becoming the type of man who affects a solemn demeanor in order to gain a wise reputation, then he takes his leave with Lorenzo. Bassanio jokes that Gratiano has terribly little to say, claiming that his friend’s wise remarks prove as elusive as “two grains of wheat hid in two bushels of chaff” (I.i.115–116). Antonio asks Bassanio to tell him about the clandestine love that Bassanio is harboring. In reply, Bassanio...

Week Three Summary
Team C Reflection
This week I learned about qualitative and quantitative analysis. Qualitative is exploratory research that helps develop an idea when there is uncertainty. This type of research is done with interviews of individual groups of people or focus groups. Quantitative research is research using numerical data. This type of research is done in bigger groups in different surveys types. Some examples are online or telephone interviews (Cooper & Schindler, 2011).
This week material helped me receive another perspective on using surveys. I enjoy taking some surveys however; when knowing I am being tested on something I tend to tense up. There is various ways to conduct surveys examples online or emails. Surveys can be simple and can be asked detailed questions depending on the research that is being explored. The way a survey is created will vary from topic-to-topic, and the outcomes will be different as well. I want to own my own business, and in order to create the right business for my area I have to research to ensure my business can survive. The material has given me the needed educational material to begin researching the required information to apply into my own potential business. When the business is established I can implement small surveys to my customers to provide feedback about my business (Cooper & Schindler, 2011).
This week we learned about...
