Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.
