Subtract 24–(—15).
Subtracting a negative number from another negative number is the same as adding the positive value of that negative number. Therefore, -(-15) is equivalent to 15, so the expression becomes 24 + 15.
Therefore, 24–(—15) = 24 + 15 = 39. Answer: \boxed{39}.
To subtract 24 - (-15), you can follow these steps:
Step 1: Simplify the expression by removing the double negative sign (-) before 15. This can be done by changing the subtraction to addition and the negative number to a positive number.
24 + 15
Step 2: Add the numbers together.
24 + 15 = 39
Therefore, 24 - (-15) is equal to 39.
