Algebra is the part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations. Algebra is the branch of mathematics in which abstract symbols, rather than numbers, are manipulated or operated with arithmetic. For example, x + y = z or b - 2 = 5 are algebraic equations, 2 + 3 = 5 and 73 * 46 = 3,358 are not. (Elementary algebra deals with the manipulation of variables as if they were numbers and is therefore essential in all applications of mathematics.) Also we use algebra because Just as multiplying two by twelve is faster than counting to 24 or adding 2 twelve times, algebra helps us solve problems more quickly and easily than we could otherwise. Algebra also opens up whole new areas of life problems, such as graphing curves that cannot be solved with only foundational math skills.
