Question:
At one time I had the answer to this math equation but I have lost it
and can't seem to regain it. I may be going at it wrong but as I recall
there were the numbers 1 through 4, and the std operators, +, -, /, *,
and parentheses. The object was to make the four numbers with the operators
equal to 7. Each number and operator may be used only once. My 9 year
old loves these quizzes but I can't give it to her if I can't provide
the correct answer.

3) + 1((4
3) / 2) +
