What is Algebra Objectives After completing this unit you should be able to: Define algebra Recognize when an algebraic statement is an algebraic term expression, or equation What is Algebra? Algebra is a branch of mathematics that uses mathematical statements to describe relationships between things that vary over time. These variables include things like the relationship between supply of an object and its price. When we use a mathematical statement to describe a relationship, we often use letters to represent the quantity that varies, since it is not a fixed amount. These letters and symbols are referred to as variables . (See the Appendix One for a brief review of constants and variables.) The mathematical statements that describe relationships are expressed using algebraic terms, expressions, or equations (mathematical statements containing letters or symbols to represent numbers). Before we use algebra to find information about these kinds of relationships, it is important to first cover some basic terminology. In this unit we will first define terms expressions , and equations . In the remaining units in this book we will review how to work with algebraic expressions, solve equations, and how to construct algebraic equations that describe a relationship. We will also introduce the notation used in algebra as we move through this unit.

Cynthia Lanius Algebra - Fun with Calendars A fun mathematical puzzle to play with your friends. (Or teachers , with your class.) Take any calendar. Tell your friend to choose 4 days that form a square like the four to the right. Your friend should tell you only the sum of the four days, and you can tell her what the four days are. How does the puzzle work? You know how people always want to see a use for algebra? Well this puzzle uses algebra. Here's what I mean. Let's pretend that the 4 numbers that the person chose were the highlighted ones here - 18, 19, 25, and 26. She adds up the four numbers and tells you only that the sum is 88. You make a couple of calculations and tell her the numbers. What calculations? Lets figure that out with algebra. Let's call the first number n . Then you know that the next number would be n + 1 and the next number would be n + 7 and the next number would be n + 8 . We had our friend add up the four numbers, so let's add our four numbers: n + n + 1 + n + 7 + n + 8 And since our friend got 88 when she added them, let's make our sum equal 88:

Please Read How You Can Help Keep the Encyclopedia Free Algebra First published Tue 29 May, 2007 Algebra is a branch of mathematics sibling to geometry, analysis (calculus), number theory, combinatorics, etc. Although algebra has its roots in numerical domains such as the reals and the complex numbers, in its full generality it differs from its siblings in serving no specific mathematical domain. Whereas geometry treats spatial entities, analysis continuous variation, number theory integer arithmetic, and combinatorics discrete structures, algebra is equally applicable to all these and other mathematical domains. Elementary algebra , in use for centuries and taught in secondary school, is the arithmetic of indefinite quantities or variables x y x y has no definite value, yet we can still say that it is always equal to y x , or to x y x y or y r r describes infinitely many possible computations, one for each possible valuation of its variables. A universally true law expresses infinitely many cases, for example the single equation x y y x summarizes the infinitely many facts 1+2 = 2+1, 3+7 = 7+3, etc. The equation 2

A separate file with all answers, fully worked, is also freely downloadable. What's Linear Algebra about? When I started teaching this subject I found three kinds of texts. There were applications books that avoid proofs and cover the linear algebra only as needed for their applications. There were advanced books that assume that students can understand their elegant proofs and know how to answer the homework questions having seen only one or two examples. And, there were books that spend a good part of the semester multiplying matrices and computing determinants and then suddenly change level to working with definitions and proofs. In my classroom each of these types was a problem. The applications were interesting but I wanted to focus on the linear algebra. The advanced books were beautiful but my students were not ready for them. And the level-switching books resulted in a lot of grief: students estimated that these were like calculus books, where there is material labelled `proof' that can skipped in favor of computations, and when the level switched no amount of prompting by me could convince them otherwise.

How the Super Tuesday States Screwed Themselves What Is the Value of Algebra? By Richard Cohen Thursday, February 16, 2006; 12:00 AM I am haunted by Gabriela Ocampo. Last year, she dropped out of the 12th grade at Birmingham High School in Los Angeles after failing algebra six times in six semesters, trying it a seventh time and finally just despairing over ever getting it. So, according to the Los Angeles Times, she "gathered her textbooks, dropped them at the campus book room and, without telling a soul, vanished from Birmingham High School." Gabriela, this is Richard: There's life after algebra. In truth, I don't know what to tell Gabriela. The L.A. school district now requires all students to pass a year of algebra and a year of geometry in order to graduate. This is something new for Los Angeles (although 17 states require it) and it is the sort of vaunted education reform that is supposed to close the science and math gap and make the U.S. more competitive. All it seems to do, though, is ruin the lives of countless kids. In L.A., more kids drop out of school on account of algebra than any other subject. I can hardly blame them. I confess to be one of those people who hate math. I can do my basic arithmetic all right (although not percentages) but I flunked algebra (once), barely passed it the second time the only proof I've ever seen of divine intervention somehow passed geometry and resolved, with a grateful exhale of breath, that I would never go near math again. I let others go on to intermediate algebra and trigonometry while I busied myself learning how to type. In due course, this came to be the way I made my living. Typing: Best class I ever took.
