( 32 − 16 ) ⋅ 33 22 = 24 (32 - 16) \cdot \frac{33}{22} =24

( 32 − 16 ) × 33 ÷ 22 = 24 (32-16)\times 33 \div 22 =24

The problem suggest all 4 operators be used. This solution fails to include +. If all 4 operators don't need to be used then the problem is poorly worded, a common problem on this site

Normally with only 4 values, one can only use 3 binary operators between them. However, I suppose one could do something like: − ( 16 + ( − 32 ) ) × 33 ÷ 22 = 24 -(16+(-32))\times 33 \div 22 = 24

The way the problem is worded, it suggests that all four operators be used. Poor wording
