Remember that only like terms can be combined. An expression in simplest form has no like terms and parentheses.
- 31p
Practice makes perfect
An expression in simplest form has no like terms and parentheses. Let's first rewrite this expression as a sum to identify all like terms.
4p - 5p - 30p
⇓
4p + ( - 5p) + ( - 30p)
Remember that like terms — constant terms or terms with the same variable and the same exponent — can be combined. In this case, we have three p-terms. We will combine like terms to simplify the expression.
