To solve the expression \( 24 - (-13) - 12 \), follow these steps:
Start with the expression: \[ 24 - (-13) - 12 \]
The double negative becomes a positive, so \( -(-13) = +13 \): \[ 24 + 13 - 12 \]
Now, add \( 24 \) and \( 13 \): \[ 24 + 13 = 37 \]
Finally, subtract \( 12 \) from \( 37 \): \[ 37 - 12 = 25 \]
So, the result of the expression \( 24 - (-13) - 12 \) is \( 25 \).
