Let’s solve each subtraction problem step by step. Remember, we’re subtracting without regrouping — that means in each column (Tens and Ones), the top number is bigger than or equal to the bottom number, so we don’t need to borrow.
We’ll go row by row, left to right.

First Row:
1.
54 - 21
- Tens: 5 - 2 = 3
- Ones: 4 - 1 = 3
→ Answer:
33
2.
68 - 40
- Tens: 6 - 4 = 2
- Ones: 8 - 0 = 8
→ Answer:
28
3.
72 - 41
- Tens: 7 - 4 = 3
- Ones: 2 - 1 = 1
→ Answer:
31

Second Row:
4.
87 - 31
- Tens: 8 - 3 = 5
- Ones: 7 - 1 = 6
→ Answer:
56
5.
45 - 23
- Tens: 4 - 2 = 2
- Ones: 5 - 3 = 2
→ Answer:
22
6.
13 - 3
- This one looks tricky because there’s no tens digit written for the second number. But “3” means 0 tens and 3 ones.
- So it’s really: 13 - 03
- Tens: 1 - 0 = 1
- Ones: 3 - 3 = 0
→ Answer:
10

Third Row:
7.
36 - 15
- Tens: 3 - 1 = 2
- Ones: 6 - 5 = 1
→ Answer:
21
8.
87 - 11
- Tens: 8 - 1 = 7
- Ones: 7 - 1 = 6
→ Answer:
76
9.
48 - 37
- Tens: 4 - 3 = 1
- Ones: 8 - 7 = 1
→ Answer:
11
