Kelly telephoned brook about a homework problem. Kelly said, “Four plus three times two is 14, isn’t it?” Brook replied, “No, it’s 10.” Did someone make a mistake? Can you explain where these two answers came from?
Kelly made a mistake by not following PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. She added 4 and 3 before multiplying it by two when the multiplication comes before the addition or subtraction. Brook is correct.
