## ** and ++Math brain teasers require computations to solve.If 3**5 = 27 but 5**3 = 35
4++8 = 20 but 8++4 = 16 Then what is the result of (8**7)++9? ## AnswerThe result is 106.For the operator **, you add 4 to the second number and then multiply, so a**b = a * (b + 4) and a++b = a + (b * 2) So therefore (8**7) ++9 = (8*(7 + 4)) ++ 9 = 88++9 = 88 + (9 *2) = 88 + 18 = 106 Hide ## What Next?
