To determine what number must be added to reach zero when starting with the provided numbers, we can consider each number individually:
-
For -4:
To reach zero, you would need to add 4: \[ -4 + 4 = 0 \] -
For 4:
To reach zero, you would need to add -4: \[ 4 + (-4) = 0 \] -
For -10:
To reach zero, you would need to add 10: \[ -10 + 10 = 0 \] -
For 10:
To reach zero, you would need to add -10: \[ 10 + (-10) = 0 \]
Thus, the numbers that must be added to reach zero for each of the given values are:
- For -4, add 4
- For 4, add -4
- For -10, add 10
- For 10, add -10
