How to make 10 using 4 fours?

You can make the number 10 using four fours with the following mathematical expression: ( (4 \times 4) - (4 + 4) ). This simplifies to ( 16 - 8 = 8 ), which is incorrect. Instead, try this: ( (4 \times 4) / 4 + 4 = 10 ). This correctly uses four fours to achieve the desired result.
