To simplify the expression \( 20 + (-30) \):
1. When you add a negative number, it is the same as subtracting that number. So, you can rewrite the expression as:
\[
20 - 30
\]
2. Now, perform the subtraction:
\[
20 - 30 = -10
\]
Thus, the simplified expression is \( -10 \).
The correct response is **-10**.
