Terms whose variables (such as x or y) with any exponents (such as the 2 in x

Examples:

7x and 2x are

3x

But 7x and 7x

Like terms can be added together.

^{2}) are the same.Examples:

7x and 2x are

**like terms**because they are both "x".3x

^{2}and −2x^{2}are**like terms**because they are both "x^{2}".But 7x and 7x

^{2}are NOT like terms (the exponents are different), they are**unlike terms**.Like terms can be added together.
