Joe was asked by a stranger to find the answer to the arithmetic problem:
8 + 5 × 2
Joe wrote the following:
8 + 5 × 2 = 13 × 2 = 26
What did Joe do wrong (other than talking to a stranger, of course)? What should the answer be?
Answer
Joe added 8 and 5 first instead of multiplying 5 and 2 first.
8 + 10 = 18
