Subtracting 2-Digit from 3-Digit Numbers With Some Regrouping (25 ... - Free Printable

Problem Description:

The task involves subtracting 2-digit numbers from 3-digit numbers. Each row contains multiple subtraction problems, and the goal is to calculate the difference for each problem.

Solution Approach:

We will solve each subtraction problem step by step. Here's the breakdown:

#### Row 1:
1. 436 - 68
- Subtract the units place: \(6 - 8\). Since 6 is less than 8, borrow 1 from the tens place (3 becomes 2, and 6 becomes 16).
- \(16 - 8 = 8\).
- Subtract the tens place: \(2 - 6\). Since 2 is less than 6, borrow 1 from the hundreds place (4 becomes 3, and 2 becomes 12).
- \(12 - 6 = 6\).
- Subtract the hundreds place: \(3 - 0 = 3\).
- Result: 368.

2. 766 - 90
- Subtract the units place: \(6 - 0 = 6\).
- Subtract the tens place: \(6 - 9\). Since 6 is less than 9, borrow 1 from the hundreds place (7 becomes 6, and 6 becomes 16).
- \(16 - 9 = 7\).
- Subtract the hundreds place: \(6 - 0 = 6\).
- Result: 676.

3. 138 - 40
- Subtract the units place: \(8 - 0 = 8\).
- Subtract the tens place: \(3 - 4\). Since 3 is less than 4, borrow 1 from the hundreds place (1 becomes 0, and 3 becomes 13).
- \(13 - 4 = 9\).
- Subtract the hundreds place: \(0 - 0 = 0\).
- Result: 98.

4. 710 - 14
- Subtract the units place: \(0 - 4\). Since 0 is less than 4, borrow 1 from the tens place (1 becomes 0, and 0 becomes 10).
- \(10 - 4 = 6\).
- Subtract the tens place: \(0 - 1 = -1\). Since 0 is less than 1, borrow 1 from the hundreds place (7 becomes 6, and 0 becomes 10).
- \(10 - 1 = 9\).
- Subtract the hundreds place: \(6 - 0 = 6\).
- Result: 696.
