Bonus (1 points) If you finish the problems early and have some extra time to
kill, try this problem. But be sure you did all the three problems correctly.
Make an expression using 3, 3, 8, 8, +, −, ×, ÷, ( and ) such that the
value of this expression is 24. You have to use each of the four numbers
exactly once, but you may use the operations and parentheses as many
times as you wish. For example, 3 − (3 + 8) + 8 is legal though the value
is not 24, but 3 × 8 is not allowed.
Answer:
8 ÷ (3 − 8 ÷ 3)
