-4

4

-10

10

Answer 1

To determine what number must be added to reach zero when starting with the provided numbers, we can consider each number individually:

1. **For -4**:
To reach zero, you would need to add 4:
\[
-4 + 4 = 0
\]

2. **For 4**:
To reach zero, you would need to add -4:
\[
4 + (-4) = 0
\]

3. **For -10**:
To reach zero, you would need to add 10:
\[
-10 + 10 = 0
\]

4. **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**
