Q:
# What Are Similar Terms in Algebra?

**Similar terms in algebra, sometimes referred to as like terms, are terms that contain the same variables raised to the same power.** In algebraic expressions, terms cannot be combined unless they are similar terms.

Combining similar terms is a way to simplify algebraic expressions in order to make them easier to work with. For example, the equation 7xy - 4xy + 4x^2 + 5x^2 can be simplified by combining its similar terms. The terms that share variables and that are raised to the same power are 7xy and -4xy, as well as 4x^2 and 5x^2. When similar terms are combined, the equation reads 3xy + 9x^2.
