Definition

Like terms are terms with the same variable raised to the same power, combined by adding their coefficients.

Examples

  • 3x and 5x are like terms: 3x + 5x = 8x.
  • 2y and -7y are like terms: 2y - 7y = -5y.

Key rule

Only like terms can be combined by adding coefficients.

Memory hook

Same variable, same power - they match.
