- I'm really having trouble finding at least one expression using all four arithmetic operators (+, - , ×, ÷) at least once.......and one expression that uses all five digits AND all four operators.

Maybe this will help it easier but I;m having little success...One expression might even use all five digits ad all four operators. For example: If you have the digits 1, 3, 5, 8, and 2,and use them to write equivalent expressions for the number 24, you could write: 3 × 8, or 23 + 1, but you cannot write: 13 × 2 − 2, because the "2" is used twice in one expression.
