Subtraction Facts to 18 (B) worksheet featuring various subtraction problems for math practice.

Problem Description:

The task involves solving a series of subtraction problems where the minuends and subtrahends are provided. The goal is to compute the differences for each subtraction fact.

Given Subtraction Problems:

The image contains three rows of subtraction problems. Let's solve them step by step.

---

Row 1:

1. \( 17 - 9 \)
- Subtract 9 from 17: \( 17 - 9 = 8 \)

2. \( 18 - 9 \)
- Subtract 9 from 18: \( 18 - 9 = 9 \)

3. \( 9 - 2 \)
- Subtract 2 from 9: \( 9 - 2 = 7 \)

4. \( 15 - 8 \)
- Subtract 8 from 15: \( 15 - 8 = 7 \)

Row 1 Answers: \( 8, 9, 7, 7 \)

---

Row 2:

1. \( 12 - 3 \)
- Subtract 3 from 12: \( 12 - 3 = 9 \)

2. \( 10 - 3 \)
- Subtract 3 from 10: \( 10 - 3 = 7 \)

3. \( 2 - 1 \)
- Subtract 1 from 2: \( 2 - 1 = 1 \)

4. \( 15 - 6 \)
- Subtract 6 from 15: \( 15 - 6 = 9 \)

Row 2 Answers: \( 9, 7, 1, 9 \)

---

Row 3:

1. \( 9 - 2 \)
- Subtract 2 from 9: \( 9 - 2 = 7 \)

2. \( 16 - 7 \)
- Subtract 7 from 16: \( 16 - 7 = 9 \)

3. \( 10 - 6 \)
- Subtract 6 from 10: \( 10 - 6 = 4 \)

4. \( 10 - 4 \)
- Subtract 4 from 10: \( 10 - 4 = 6 \)

Row 3 Answers: \( 7, 9, 4, 6 \)

---

Final Answer:

Combining all the answers from the three rows:

- Row 1: \( 8, 9, 7, 7 \)
- Row 2: \( 9, 7, 1, 9 \)
- Row 3: \( 7, 9, 4, 6 \)

\[
\boxed{8, 9, 7, 7, 9, 7, 1, 9, 7, 9, 4, 6}
\]
