3 3 8 8 using + - / x or fractions = 24?

Number Theory Level 2

Using the digits 3, 3, 8, 8 each once (only once in any order) and using some/all of +-x÷ () , can you make 24?

E.g. 8+(3÷3)+8=17 (We need 24)

Impossible. Possible.

You are implicitly using parentheses. Doing so significantly changes the nature of the problem.

The expression 8 ÷ 3 - 8 ÷ 3 simplifies to 0. To execute the subtraction before the division requires either parentheses or a fractional notation that also was not included in the question.
