To solve the expression \( 15 + (-5) + (-10) \), follow these steps:

1. Start with the first number: \( 15 \).
2. Add the second number: \( 15 + (-5) \).

\[ 15 + (-5) = 15 - 5 = 10 \]

3. Add the third number to the result: \( 10 + (-10) \).

\[ 10 + (-10) = 10 - 10 = 0 \]

So, the solution to the expression \( 15 + (-5) + (-10) \) is \( 0 \).
