To solve the given problems by changing subtraction to the addition of the additive inverse, we will follow these steps:

1. Identify the subtraction operation in each expression.
2. Replace the subtraction with the addition of the additive inverse (i.e., $$ a - b $$ becomes $$ a + (-b) $$).
3. Perform the calculations.

Let's go through each expression step by step.

### First Set of Expressions

1. **a)** $$ 7 - (-3) $$  
   Change to addition: $$ 7 + 3 = 10 $$

2. **b)** $$ 10 - 8 $$  
   Change to addition: $$ 10 + (-8) = 10 - 8 = 2 $$

3. **c)** $$ 7 - 10 $$  
   Change to addition: $$ 7 + (-10) = 7 - 10 = -3 $$

4. **d)** $$ 15 - (-9) $$  
   Change to addition: $$ 15 + 9 = 24 $$

5. **e)** $$ 9 - 15 $$  
   Change to addition: $$ 9 + (-15) = 9 - 15 = -6 $$

6. **f)** $$ 9 - (-15) $$  
   Change to addition: $$ 9 + 15 = 24 $$

7. **g)** $$ -9 - (-15) $$  
   Change to addition: $$ -9 + 15 = 6 $$

8. **h)** $$ -15 - (-9) $$  
   Change to addition: $$ -15 + 9 = -6 $$

9. **i)** $$ 13 - (-13) $$  
   Change to addition: $$ 13 + 13 = 26 $$

10. **j)** $$ 16 - 21 $$  
    Change to addition: $$ 16 + (-21) = 16 - 21 = -5 $$

11. **k)** $$ 16 - (-21) $$  
    Change to addition: $$ 16 + 21 = 37 $$

12. **l)** $$ -16 - (-21) $$  
    Change to addition: $$ -16 + 21 = 5 $$

13. **m)** $$ 12 - (-5) + 8 $$  
    Change to addition: $$ 12 + 5 + 8 = 25 $$

14. **n)** $$ 10 - (-6) + 4 $$  
    Change to addition: $$ 10 + 6 + 4 = 20 $$

15. **o)** $$ -12 - (-15) + 3 $$  
    Change to addition: $$ -12 + 15 + 3 = 6 $$

### Second Set of Expressions

1. **a)** $$ 14 - 8 + (-6) $$  
   Change to addition: $$ 14 + (-8) + (-6) = 14 - 8 - 6 = 0 $$

2. **b)** $$ -(-13) + (-17) $$  
   Change to addition: $$ 13 - 17 = -4 $$

3. **c)** $$ 100 - (-5) - 5 $$  
   Change to addition: $$ 100 + 5 - 5 = 100 $$

4. **d)** $$ 12 - (-4) - (-6) $$  
   Change to addition: $$ 12 + 4 + 6 = 22 $$

5. **e)** $$ -(-5) - 10 - (-12) $$  
   Change to addition: $$ 5 - 10 + 12 = 7 $$

6. **f)** $$ 12 - 6 - (-7) - 5 $$  
   Change to addition: $$ 12 - 6 + 7 - 5 = 8 $$

7. **g)** $$ -13 - 18 - 5 - (-24) $$  
   Change to addition: $$ -13 - 18 - 5 + 24 = -12 $$

8. **h)** $$ 5 - 3 - (-9) - 7 - 3 $$  
   Change to addition: $$ 5 - 3 + 9 - 7 - 3 = 1 $$
