Let's solve each subtraction problem by rewriting it into an addition problem where we add the opposite.
#### Problem 8:
[tex]\[ 14 - 6 \][/tex]
Rewrite this as:
[tex]\[ 14 + (-6) \][/tex]
Calculating this, we get:
[tex]\[ 14 + (-6) = 8 \][/tex]
So,
[tex]\[ 14 - 6 = 8 \][/tex]
#### Problem 13:
[tex]\[ 2 - (-3) \][/tex]
Rewrite this as:
[tex]\[ 2 + 3 \][/tex]
Calculating this, we get:
[tex]\[ 2 + 3 = 5 \][/tex]
So,
[tex]\[ 2 - (-3) = 5 \][/tex]
#### Problem 14:
[tex]\[ -3 - 2 \][/tex]
Rewrite this as:
[tex]\[ -3 + (-2) \][/tex]
Calculating this, we get:
[tex]\[ -3 + (-2) = -5 \][/tex]
So,
[tex]\[ -3 - 2 = -5 \][/tex]
#### Problem 15:
[tex]\[ -4 - (-5) \][/tex]
Rewrite this as:
[tex]\[ -4 + 5 \][/tex]
Calculating this, we get:
[tex]\[ -4 + 5 = 1 \][/tex]
So,
[tex]\[ -4 - (-5) = 1 \][/tex]
#### Problem 16:
[tex]\[ 2 - 5 \][/tex]
Rewrite this as:
[tex]\[ 2 + (-5) \][/tex]
Calculating this, we get:
[tex]\[ 2 + (-5) = -3 \][/tex]
So,
[tex]\[ 2 - 5 = -3 \][/tex]
#### Problem 17:
[tex]\[ 3 - (-3) \][/tex]
Rewrite this as:
[tex]\[ 3 + 3 \][/tex]
Calculating this, we get:
[tex]\[ 3 + 3 = 6 \][/tex]
So,
[tex]\[ 3 - (-3) = 6 \][/tex]
#### Problem 18:
[tex]\[ 4 - (-3) \][/tex]
Rewrite this as:
[tex]\[ 4 + 3 \][/tex]
Calculating this, we get:
[tex]\[ 4 + 3 = 7 \][/tex]
So,
[tex]\[ 4 - (-3) = 7 \][/tex]
#### Problem 19:
[tex]\[ -7 - (-2) \][/tex]
Rewrite this as:
[tex]\[ -7 + 2 \][/tex]
Calculating this, we get:
[tex]\[ -7 + 2 = -5 \][/tex]
So,
[tex]\[ -7 - (-2) = -5 \][/tex]
#### Problem 20:
[tex]\[ -9 - 1 \][/tex]
Rewrite this as:
[tex]\[ -9 + (-1) \][/tex]
Calculating this, we get:
[tex]\[ -9 + (-1) = -10 \][/tex]
So,
[tex]\[ -9 - 1 = -10 \][/tex]
#### Problem 21:
[tex]\[ 0 - (-9) \][/tex]
Rewrite this as:
[tex]\[ 0 + 9 \][/tex]
Calculating this, we get:
[tex]\[ 0 + 9 = 9 \][/tex]
So,
[tex]\[ 0 - (-9) = 9 \][/tex]
Summarizing all our results:
1. [tex]\( 14 - 6 = 8 \)[/tex]
2. [tex]\( 2 - (-3) = 5 \)[/tex]
3. [tex]\( -3 - 2 = -5 \)[/tex]
4. [tex]\( -4 - (-5) = 1 \)[/tex]
5. [tex]\( 2 - 5 = -3 \)[/tex]
6. [tex]\( 3 - (-3) = 6 \)[/tex]
7. [tex]\( 4 - (-3) = 7 \)[/tex]
8. [tex]\( -7 - (-2) = -5 \)[/tex]
9. [tex]\( -9 - 1 = -10 \)[/tex]
10. [tex]\( 0 - (-9) = 9 \)[/tex]
