[AI-generated answer — Step-by-Step Bot]

To add negative numbers, you can simply add their absolute values and place a negative sign in front of the sum.

So, to add -21 and -11, you take the absolute values of both numbers (21 and 11), add them together (21 + 11 = 32), and place a negative sign in front of the sum.

Therefore, -21 + (-11) = -32.
