Subtraction practice worksheet with 16 problems for elementary students.

Problem Description:

The task involves solving a series of subtraction problems. Each problem consists of two numbers, and the goal is to subtract the second number from the first number in each case.

Solution Approach:

We will solve each subtraction problem step by step. Let's go through each row one by one.

---

#### Row 1:
1. 482 - 246
- Subtract digit by digit from right to left.
- \( 2 - 6 \): Borrow 1 from the tens place (8 becomes 7), so \( 12 - 6 = 6 \).
- \( 7 - 4 = 3 \).
- \( 4 - 2 = 2 \).
- Result: 236

2. 840 - 524
- \( 0 - 4 \): Borrow 1 from the tens place (4 becomes 3), so \( 10 - 4 = 6 \).
- \( 3 - 2 = 1 \).
- \( 8 - 5 = 3 \).
- Result: 316

3. 586 - 496
- \( 6 - 6 = 0 \).
- \( 8 - 9 \): Borrow 1 from the hundreds place (5 becomes 4), so \( 18 - 9 = 9 \).
- \( 4 - 4 = 0 \).
- Result: 90

4. 726 - 157
- \( 6 - 7 \): Borrow 1 from the tens place (2 becomes 1), so \( 16 - 7 = 9 \).
- \( 1 - 5 \): Borrow 1 from the hundreds place (7 becomes 6), so \( 11 - 5 = 6 \).
- \( 6 - 1 = 5 \).
- Result: 569

#### Row 2:
1. 845 - 374
- \( 5 - 4 = 1 \).
- \( 4 - 7 \): Borrow 1 from the hundreds place (8 becomes 7), so \( 14 - 7 = 7 \).
- \( 7 - 3 = 4 \).
- Result: 471

2. 664 - 489
- \( 4 - 9 \): Borrow 1 from the tens place (6 becomes 5), so \( 14 - 9 = 5 \).
- \( 5 - 8 \): Borrow 1 from the hundreds place (6 becomes 5), so \( 15 - 8 = 7 \).
- \( 5 - 4 = 1 \).
- Result: 175

3. 304 - 267
- \( 4 - 7 \): Borrow 1 from the tens place (0 becomes 9), so \( 14 - 7 = 7 \).
- \( 9 - 6 = 3 \).
- \( 3 - 2 = 1 \).
- Result: 37
