Algebra is a branch of mathematics that studies the relationships and operations between numbers, variables and other mathematical symbols. In algebra, we use letters or symbols to represent unknown numbers or variables. The basic concepts of algebra involve mathematical operations such as addition, subtraction, multiplication, and division.
One of the basic concepts in algebra is equations. An equation is a mathematical statement that expresses equality between two mathematical expressions. Equations are often used to find the value of an unknown variable. For example, in a simple equation like “2x + 5 = 15”, we can find the value of x using algebraic operations.
