56-(29-27)+15

To solve the expression \( 56 - (29 - 27) + 15 \), we follow the order of operations:

1. First, solve the expression inside the parentheses: \( 29 - 27 = 2 \).
2. Now substitute that value back into the expression: \( 56 - 2 + 15 \).
3. Next, perform the subtraction: \( 56 - 2 = 54 \).
4. Finally, add \( 15 \) to \( 54 \): \( 54 + 15 = 69 \).

So, the final result is \( 69 \).
