# Term

Pronunciation: /tɜrm/ Explain

A term is a part of an expression that is separated from other terms by addition or subtraction. A term consists of a coefficient and zero or more variables. Terms are enumerated (counted) from left to right. ### Constant Term

A constant term of an expression is a term without any variables. In the expression 3x2 + 5x - 2, the constant term is -2.

### Like Terms

Two terms are like terms if they have the same variable(s) and each variable has the same exponent. 3x2 is like 5x2 because the variable x is both, and the exponent of x is 2 in both.
