Algebra is a type of mathematics where symbols are used to represent amounts that are unknown. These
unknown quantities are generally combined with mathematical operations (addition, subtraction, multiplication,division, square root, cube root, exponents, etc) to form statements that describe the relationship of things that change over a period of time. These statements are expressed using equations, expressions and terms. Problems can be solved by translating words into algebraic equations. The description of a problem using an equation and other mathematical concepts is known as a mathematical model. A mathematical model can be used to solve numerous types of problems in every day life
