Step-by-step solution for: Subtracting 2-Digit Numbers With All Regrouping (25 Questions ...
Let’s work through each subtraction problem one by one. We’ll line up the numbers by place value (ones under ones, tens under tens, etc.) and subtract carefully. If we need to borrow, we’ll do that step by step.

Row 1:
1. 910 - 42
Start from the right:
0 - 2 → can’t do, so borrow from tens. But tens is 1, so borrow from hundreds.
Hundreds: 9 becomes 8
Tens: 1 becomes 11, then lend 1 to ones → tens becomes 10, ones becomes 10
Now:
Ones: 10 - 2 = 8
Tens: 10 - 4 = 6
Hundreds: 8 - 0 = 8
→ 868
2. 174 - 86
Ones: 4 - 6 → borrow from tens
Tens: 7 becomes 6, ones becomes 14
14 - 6 = 8
Tens: 6 - 8 → can’t do, borrow from hundreds
Hundreds: 1 becomes 0, tens becomes 16
16 - 8 = 8
Hundreds: 0 - 0 = 0
→ 88
3. 321 - 93
Ones: 1 - 3 → borrow from tens
Tens: 2 becomes 1, ones becomes 11
11 - 3 = 8
Tens: 1 - 9 → borrow from hundreds
Hundreds: 3 becomes 2, tens becomes 11
11 - 9 = 2
Hundreds: 2 - 0 = 2
→ 228
4. 633 - 77
Ones: 3 - 7 → borrow from tens
Tens: 3 becomes 2, ones becomes 13
13 - 7 = 6
Tens: 2 - 7 → borrow from hundreds
Hundreds: 6 becomes 5, tens becomes 12
12 - 7 = 5
Hundreds: 5 - 0 = 5
→ 556
5. 980 - 91
Ones: 0 - 1 → borrow from tens
Tens: 8 becomes 7, ones becomes 10
10 - 1 = 9
Tens: 7 - 9 → borrow from hundreds
Hundreds: 9 becomes 8, tens becomes 17
17 - 9 = 8
Hundreds: 8 - 0 = 8
→ 889

Ones: 3 - 5 → borrow from tens
Tens: 2 becomes 1, ones becomes 13

→ 69
9. 900 - 11
Ones: 0 - 1 → borrow from tens → but tens is 0, so borrow from hundreds
Hundreds: 9 becomes 8, tens becomes 10, then lend to ones → tens becomes 9, ones becomes 10
Ones: 10 - 1 = 9
Tens: 9 - 1 = 8
Hundreds: 8 - 0 = 8
→ 889
10. 320 - 52
