Add (−34) and (12).(1 point)
To add (-21) and (-11), you simply add the two numbers together.
(-21) + (-11) = -32
So, the sum of (-21) and (-11) is -32.
To add two numbers, you simply take their sum. In this case, you need to add (-21) and (-11).
When adding two negative numbers, you can think of it as subtracting the absolute values of the numbers, but keeping the negative sign.
So to add (-21) and (-11):
1. Ignore the negative signs temporarily and add the absolute values of the numbers:
|-21| + |-11| = 21 + 11 = 32
2. Since both numbers are negative, the sum will also be negative. So, put the negative sign back:
-32
Therefore, the sum of (-21) and (-11) is -32.
