Let’s work through the math problems one by one. These are all about adding and subtracting integers — that means positive and negative whole numbers.
Remember these simple rules:
- Adding a negative is like subtracting: 5 + (-3) = 5 - 3
- Subtracting a negative is like adding: 5 - (-3) = 5 + 3
- When you add two negatives, keep the minus sign and add the numbers: -2 + (-4) = -6
- When signs are different, subtract the smaller number from the bigger one and take the sign of the bigger number: -7 + 3 → 7 - 3 = 4, but since 7 was negative, answer is -4
Now let’s solve each problem carefully:
Left column (top to bottom):
1. 5 + (-8) → 5 - 8 =
-3
2. -2 - (-10) → -2 + 10 =
8
3. -9 + 15 → 15 - 9 =
6 (positive because 15 is bigger)
4. 8 + (-7) → 8 - 7 =
1
5. -6 - 4 → -6 - 4 =
-10
6. 2 - (-10) → 2 + 10 =
12
7. 4 + (-6) → 4 - 6 =
-2
Bottom left section:
8. -2 - (-9) → -2 + 9 =
7
9. 11 + (-7) → 11 - 7 =
4
10. 4 + (-10) → 4 - 10 =
-6
11. 2 - 14 → 2 - 14 =
-12
12. -3 - (-4) → -3 + 4 =
1
13. -5 + (-4) → -5 - 4 =
-9
Middle bottom section:
14. 3 - 1 =
2
15. 8 - (-2) → 8 + 2 =
10
16. 15 + (-12) → 15 - 12 =
3
17. 4 + 8 =
12
18. -11 - (-4) → -11 + 4 =
-7
19. -3 + 12 → 12 - 3 =
9
Right bottom section:
20. 7 - 11 =
-4
21. -8 - 3 =
-11
22. 10 + (-6) → 10 - 6 =
4
23. -9 - (-4) → -9 + 4 =
-5
24. -3 - (-2) → -3 + 2 =
-1
25. -3 + (-5) → -3 - 5 =
-8
All answers checked and verified.
Final Answer:
-3, 8, 6, 1, -10, 12, -2, 7, 4, -6, -12, 1, -9, 2, 10, 3, 12, -7, 9, -4, -11, 4, -5, -1, -8
