Order of operations, step by step

Order of operations is the agreement that keeps everyone getting the same answer from the same expression.

The question

5 × ( 18 − 18 )

5×(1818)
5×0
0
  1. Work inside the brackets first. 18 − 18 = 0.
  2. × and ÷ come before + and −, so this goes first. 5 × 0 = 0.
  3. Nothing is left to work out, so the answer is 0.
