Let’s solve each problem step by step. Remember: subtracting a negative number is the same as adding its positive version.
---
A.) (-7) - (-2)
This means: start at -7, and subtract -2 → which is the same as adding +2.
So: -7 + 2 =
-5
Check on number line: Start at -7, move 2 steps to the right → lands on -5. ✔️
---
B.) (-3) - (-6)
Subtracting -6 is like adding +6.
So: -3 + 6 =
3
Check: Start at -3, move 6 steps right → passes 0, ends at 3. ✔️
---
C.) 5 - (-4)
Subtracting -4 is like adding +4.
So: 5 + 4 =
9
Check: Start at 5, move 4 steps right → lands on 9. ✔️
---
D.) (-1) - (-9)
Subtracting -9 is like adding +9.
So: -1 + 9 =
8
Check: Start at -1, move 9 steps right → passes 0, ends at 8. ✔️
---
E.) 8 - (-2)
Subtracting -2 is like adding +2.
So: 8 + 2 =
10
Check: Start at 8, move 2 steps right → lands on 10. ✔️

Final Answer:
A.) -5
B.) 3
C.) 9
D.) 8
E.) 10
