Let's solve the given mathematical expressions step by step and compare them by using \( > \), \( < \), or \( = \).

### Problem (a):
\[
(10 + 6) - 2 \quad \Box \quad 10 + (6 - 2)
\]

1. Evaluate both sides:
   - Left side: \( (10 + 6) - 2 = 16 - 2 = 14 \)
   - Right side: \( 10 + (6 - 2) = 10 + 4 = 14 \)

Thus, \( 14 = 14 \). So the correct symbol is \( = \).

### Problem (b):
\[
2 + (4 + 10) \quad \Box \quad (2 + 4) + 10
\]

1. Evaluate both sides:
   - Left side: \( 2 + (4 + 10) = 2 + 14 = 16 \)
   - Right side: \( (2 + 4) + 10 = 6 + 10 = 16 \)

Thus, \( 16 = 16 \). So the correct symbol is \( = \).

### Problem (c):
\[
11 - (6 - 1) \quad \Box \quad 11 - 6 - 1
\]

1. Evaluate both sides:
   - Left side: \( 11 - (6 - 1) = 11 - 5 = 6 \)
   - Right side: \( 11 - 6 - 1 = 5 - 1 = 4 \)

Thus, \( 6 > 4 \). So the correct symbol is \( > \).

### Final answers:
- (a) \( = \)
- (b) \( = \)
- (c) \( > \)

Would you like further explanation on any of these? Here are 5 related questions for further exploration:

1. Can you explain why parentheses affect the outcome in these expressions?
2. What is the order of operations, and why is it important in problems like these?
3. How would these expressions change if we used subtraction instead of addition?
4. Can expressions like this be solved without parentheses? How would that affect the results?
5. How do comparison symbols \( > \), \( < \), and \( = \) help in understanding relationships between numbers?

**Tip**: Always resolve operations inside parentheses first and follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
