Subtraction of integers worksheet with 12 problems for learning integer arithmetic.

Let’s solve each subtraction problem step by step. Remember the rule:
Subtracting a number is the same as adding its opposite.
So, for example:
- 93 - (-4) becomes 93 + 4
- 18 - 41 becomes 18 + (-41)
We’ll apply this to every problem.

---

Problem 1: 93 - (-4)
→ Change subtraction of negative to addition: 93 + 4 = 97

Problem 2: 44 - (-28)
→ 44 + 28 = 72

Problem 3: -20 - 24
→ This is like -20 + (-24) = -44

Problem 4: 87 - 36
→ Just subtract: 87 - 36 = 51

Problem 5: 18 - 41
→ 18 + (-41) = -23

Problem 6: 34 - (-5)
→ 34 + 5 = 39

Problem 7: -45 - 31
→ -45 + (-31) = -76

Problem 8: 51 - 51
→ Any number minus itself is 0

Problem 9: 96 - 83
→ 96 - 83 = 13

Problem 10: -54 - 18
→ -54 + (-18) = -72

Problem 11: -78 - (-37)
→ -78 + 37 = Let’s think: 78 - 37 = 41, but since 78 is bigger and negative, answer is -41

Wait — let me double-check that:
-78 + 37 → Start at -78, move 37 right → still negative.
78 - 37 = 41 → so yes, -41

Problem 12: 56 - (-34)
→ 56 + 34 = 90

Now let’s list all answers in order:

1. 97
2. 72
3. -44
4. 51
5. -23
6. 39
7. -76
8. 0
9. 13
10. -72
11. -41
12. 90

Double-checked all calculations — they’re correct.

Final Answer:
1. 97
2. 72
3. -44
4. 51
5. -23
6. 39
7. -76
8. 0
9. 13
10. -72
11. -41
