Threes and SevensMath brain teasers require computations to solve.
Using the four digits 3,3,7,7 and the mathematical operators +,-,*,/ write an expression equal to 24. You must use each digit exactly once, but may use each operator multiple times, or not at all. Parentheses are allowed. The following would be a valid expression:
(7 + 3)/(7 + 3) = 1
Answer(3 + 3/7) * 7 = 24
