Problem Analysis:


The image provided is a math worksheet focusing on subtraction facts. The task involves solving subtraction problems and determining the truth of a bonus equation.

#### Key Components:
1. Subtraction Problems: Each row contains subtraction problems where a number is subtracted from another.
2. Bonus Question: Determine whether the equation \( 10 - 10 = 0 \) is true or false.

---

Step-by-Step Solution:



#### 1. Solve Each Subtraction Problem:
We will solve each subtraction problem systematically.

##### First Row:
- \( 15 - 10 = 5 \)
- \( 12 - 2 = 10 \)
- \( 18 - 10 = 8 \)
- \( 11 - 1 = 10 \)
- \( 14 - 10 = 4 \)

##### Second Row:
- \( 17 - 10 = 7 \)
- \( 14 - 4 = 10 \)
- \( 10 - 10 = 0 \)
- \( 11 - 10 = 1 \)
- \( 17 - 7 = 10 \)

##### Third Row:
- \( 12 - 10 = 2 \)
- \( 16 - 6 = 10 \)
- \( 10 - 0 = 10 \)
- \( 17 - 7 = 10 \)
- \( 13 - 10 = 3 \)

##### Fourth Row:
- \( 16 - 10 = 6 \)
- \( 18 - 4 = 14 \)
- \( 14 - 10 = 4 \)
- \( 14 - 10 = 4 \)
- \( 19 - 9 = 10 \)

---

#### 2. Bonus Question: Is \( 10 - 10 = 0 \) True or False?
- Subtracting any number from itself results in zero.
- Therefore, \( 10 - 10 = 0 \) is true.

---

Final Answer:


- Subtraction Results:
- First Row: \( 5, 10, 8, 10, 4 \)
- Second Row: \( 7, 10, 0, 1, 10 \)
- Third Row: \( 2, 10, 10, 10, 3 \)
- Fourth Row: \( 6, 14, 4, 4, 10 \)

- Bonus Answer: Circle True for \( 10 - 10 = 0 \).

\[
\boxed{\text{True}}
\]
