Basics of Algebra
Algebra is a division of mathematics designed to help solve certain types of problems quicker and easier. Algebra is based on the concept of unknown values called variables, unlike arithmetic which is based entirely on known number values.
the equation is the important algebraic concept. it is construct from numbers, or constants and variable.
A variable is an an unknown number represented by any letter in the alphabet (often x). The value of each variable must remain the same in each problem.
Several symbols are used to relate all of the variables and constants together. These symbols are listed and explained below.
