Break Apart to Subtract math worksheet with nine subtraction exercises using visual decomposition.

The task involves solving subtraction problems using the "break apart" method. This method helps simplify subtraction by breaking numbers into smaller, more manageable parts (usually tens and ones). Let's solve each problem step by step.

Problem 1: 48 - 23 = ?

#### Step 1: Break apart the numbers
- Break 48 into 40 + 8.
- Break 23 into 20 + 3.

#### Step 2: Subtract the tens
- 40 - 20 = 20

#### Step 3: Subtract the ones
- 8 - 3 = 5

#### Step 4: Combine the results
- 20 + 5 = 25

Answer: 48 - 23 = 25

Problem 2: 56 - 34 = ?

#### Step 1: Break apart the numbers
- Break 56 into 50 + 6.
- Break 34 into 30 + 4.

#### Step 2: Subtract the tens
- 50 - 30 = 20

#### Step 3: Subtract the ones
- 6 - 4 = 2

#### Step 4: Combine the results
- 20 + 2 = 22

Answer: 56 - 34 = 22

Problem 3: 71 - 19 = ?

#### Step 1: Break apart the numbers
- Break 71 into 70 + 1.
- Break 19 into 10 + 9.

#### Step 2: Subtract the tens
- 70 - 10 = 60

#### Step 3: Subtract the ones
- 1 - 9 requires borrowing:
- Rewrite 71 as 60 + 11 (borrow 1 ten from 70 to make 11 ones).
- Now subtract: 11 - 9 = 2

#### Step 4: Combine the results
- 60 + 2 = 52

Answer: 71 - 19 = 52

Problem 4: 86 - 42 = ?

#### Step 1: Break apart the numbers
- Break 86 into 80 + 6.
- Break 42 into 40 + 2.

#### Step 2: Subtract the tens
- 80 - 40 = 40

#### Step 3: Subtract the ones
- 6 - 2 = 4

#### Step 4: Combine the results
- 40 + 4 = 44

Answer: 86 - 42 = 44

Problem 5: 68 - 47 = ?

#### Step 1: Break apart the numbers
- Break 68 into 60 + 8.
- Break 47 into 40 + 7.

#### Step 2: Subtract the tens
- 60 - 40 = 20

#### Step 3: Subtract the ones
- 8 - 7 = 1

#### Step 4: Combine the results
- 20 + 1 = 21

Answer: 68 - 47 = 21

Problem 6: 37 - 12 = ?

#### Step 1: Break apart the numbers
- Break 37 into 30 + 7.
- Break 12 into 10 + 2.

#### Step 2: Subtract the tens
- 30 - 10 = 20

#### Step 3: Subtract the ones
- 7 - 2 = 5

#### Step 4: Combine the results
- 20 + 5 = 25

Answer: 37 - 12 = 25

Problem 7: 49 - 24 = ?

#### Step 1: Break apart the numbers
- Break 49 into 40 + 9.
- Break 24 into 20 + 4.

#### Step 2: Subtract the tens
- 40 - 20 = 20

#### Step 3: Subtract the ones
- 9 - 4 = 5

#### Step 4: Combine the results
- 20 + 5 = 25

Answer: 49 - 24 = 25

---

Problem 8: 99 - 31 = ?

#### Step 1: Break apart the numbers
- Break 99 into 90 + 9.
- Break 31 into 30 + 1.

#### Step 2: Subtract the tens
- 90 - 30 = 60

#### Step 3: Subtract the ones
- 9 - 1 = 8

#### Step 4: Combine the results
- 60 + 8 = 68

Answer: 99 - 31 = 68
