Algebra Definition

Algebra is a branch of mathematics in which alphabetic letters (a - z) symbolize the value or an expression of a number. The symbols used in algebra represent the number without any fixed value, also known as a variable.

Moreover, When an equivalent sign (=) is used with those variables, those expressions became an equation.

For better understanding, let us have a very simple example.

Suppose an equation using a variable: 5 + 6 = x. In this case, x = 11, or it can also be written as "x equals to five." It is called solving an algebraic equation for x.
