An algebraic expression is an expression consisting of one or more letters, or variables. In maths there are times when we need to work out a sum or expression and we don’t have all the information that we need. When this happens, we need to find a way to include this information despite the fact that we don’t actually know what it actually is.
We break down the different parts of algebraic expressions. So far we have been talking about variables but we haven’t touched coefficients and constants.
The terms having the same literal (variable) with same exponents are called Like terms. Unlike terms are terms having the same variable with different exponents or different variable with same exponents.
An exponent is a number or letter written above and to the right of a mathematical expression called the base. It indicates that the base is to be raised to a certain power. x is the base and n is the exponent or power. This lesson looks the rules that help us solve expressions and equations with...
