Algebra is a branch of mathematics that uses letters of the alphabet to represent objects, numbers or even groups of numbers or expressions. In many cases, algebra uses shorthand mathematical notation to simplify complex or very large terms. A major goal in algebra is to solve equations.
I've found that knowing about Algebra has been very useful. Understanding algebraic methods is important in science, computing and other math courses. Algebra is used in so many fields that the subject can even help in your career.
The purpose of these lessons is to help you gain understanding the basics of Algebra, such that you do well in school and become a champion in the subject.
