What are like terms?

Like terms are terms that share these two features:

  • Same letters. (algebraic variables).
  • Same exponents.

If two terms are like terms, then they can be either added or subtracted.

The like terms for this problem are given as follows:

1.) -4n and 18n -> algebraic variable of n, exponent of 1.

2.) 15ab and 2ab -> algebraic variable of ab, exponent of 1.

5.) 14h and -3h -> algebraic variable of h, exponent of 1.

For example, the pair in item 3 is of terms that are not like terms, as they have different algebraic variables, f and 1.
