We want to add two expressions.
(1/3n + 2/3) + (- 1/6n + 1/6m)The first step in simplifying this expression is to identify which, if any, terms can be combined. Remember, only like terms — constant terms or terms with the same variable — can be combined.
( 1/3n + 2/3) + ( - 1/6n + 1/6m)
In this case, we have two n-terms, one m-term, and one constant. Only the n-terms can be combined, so to simplify the expression we will rearrange it according to the Commutative Property of Addition and then combine like terms.
