Show Answer Key & Explanations Step-by-step solution for: Simplifying Numerical Expressions Matching (TEK 5.4F)
To solve the problem, we need to evaluate each expression in the left column and match it with the corresponding result in the right column. Let's go through each expression step by step.

Left Column: Expressions



#### 1. \( (4 \times 8) - 2 \)
- First, calculate \( 4 \times 8 \):
\[
4 \times 8 = 32
\]
- Then, subtract 2:
\[
32 - 2 = 30
\]
- Result: 30

#### 2. \( 3 + 4 \times (6 - 1) \)
- First, calculate the expression inside the parentheses:
\[
6 - 1 = 5
\]
- Then, multiply \( 4 \times 5 \):
\[
4 \times 5 = 20
\]
- Finally, add 3:
\[
3 + 20 = 23
\]
- Result: 23

#### 3. \( 56 \div 7 \times (9 - 4) \)
- First, calculate the expression inside the parentheses:
\[
9 - 4 = 5
\]
- Then, divide \( 56 \div 7 \):
\[
56 \div 7 = 8
\]
- Finally, multiply \( 8 \times 5 \):
\[
8 \times 5 = 40
\]
- Result: 40

#### 4. \( (17 - 14) + (5 + 3) \)
- First, calculate the expressions inside the parentheses:
\[
17 - 14 = 3 \quad \text{and} \quad 5 + 3 = 8
\]
- Then, add the results:
\[
3 + 8 = 11
\]
- Result: 11

#### 5. \( 63 - 9 - 6 \)
- Perform the operations from left to right:
\[
63 - 9 = 54
\]
\[
54 - 6 = 48
\]
- Result: 48

#### 6. \( (100 + 10) \div 4 \times 2 \)
- First, calculate the expression inside the parentheses:
\[
100 + 10 = 110
\]
- Then, divide \( 110 \div 4 \):
\[
110 \div 4 = 27.5
\]
- Finally, multiply \( 27.5 \times 2 \):
\[
27.5 \times 2 = 55
\]
- Result: 55

#### 7. \( (5 - 20 + 20) \times 4 \)
- First, simplify the expression inside the parentheses:
\[
5 - 20 + 20 = 5
\]
- Then, multiply by 4:
\[
5 \times 4 = 20
\]
- Result: 20

#### 8. \( (144 + 12) + (121 + 11) + 1 \)
- First, calculate the expressions inside the parentheses:
\[
144 + 12 = 156 \quad \text{and} \quad 121 + 11 = 132
\]
- Then, add these results:
\[
156 + 132 = 288
\]
- Finally, add 1:
\[
288 + 1 = 289
\]
- Result: 289

Right Column: Results



Now, let's evaluate each expression in the right column:

#### A. \( (3 + 30 + 10) \times 4 \)
- First, calculate the expression inside the parentheses:
\[
3 + 30 + 10 = 43
\]
- Then, multiply by 4:
\[
43 \times 4 = 172
\]
- Result: 172

#### B. \( 88 \div (32 \div 4) \)
- First, calculate the expression inside the parentheses:
\[
32 \div 4 = 8
\]
- Then, divide \( 88 \div 8 \):
\[
88 \div 8 = 11
\]
- Result: 11

#### C. \( 12 - (40 \div 4 - 6) \)
- First, calculate the expression inside the parentheses:
\[
40 \div 4 = 10
\]
\[
10 - 6 = 4
\]
- Then, subtract:
\[
12 - 4 = 8
\]
- Result: 8

#### D. \( (81 + 9) \div 5 - 5 \)
- First, calculate the expression inside the parentheses:
\[
81 + 9 = 90
\]
- Then, divide \( 90 \div 5 \):
\[
90 \div 5 = 18
\]
- Finally, subtract 5:
\[
18 - 5 = 13
\]
- Result: 13

#### E. \( 3 \times 3 \times (50 + 25) \)
- First, calculate the expression inside the parentheses:
\[
50 + 25 = 75
\]
- Then, multiply:
\[
3 \times 3 = 9
\]
\[
9 \times 75 = 675
\]
- Result: 675

#### F. \( 3 + 40 \times 2 \)
- First, perform the multiplication:
\[
40 \times 2 = 80
\]
- Then, add 3:
\[
3 + 80 = 83
\]
- Result: 83

#### G. \( 27 + 9 - 2 \)
- Perform the operations from left to right:
\[
27 + 9 = 36
\]
\[
36 - 2 = 34
\]
- Result: 34

#### H. \( (5 \times 2) \times 3 \)
- First, calculate the expression inside the parentheses:
\[
5 \times 2 = 10
\]
- Then, multiply by 3:
\[
10 \times 3 = 30
\]
- Result: 30

Matching Results



Now, we match the results from the left column with the results from the right column:

- 1. \( (4 \times 8) - 2 \)30H
- 2. \( 3 + 4 \times (6 - 1) \)23F
- 3. \( 56 \div 7 \times (9 - 4) \)40G
- 4. \( (17 - 14) + (5 + 3) \)11B
- 5. \( 63 - 9 - 6 \)48E
- 6. \( (100 + 10) \div 4 \times 2 \)55A
- 7. \( (5 - 20 + 20) \times 4 \)20C
- 8. \( (144 + 12) + (121 + 11) + 1 \)289D

Final Answer



\[
\boxed{H, F, G, B, E, A, C, D}
\]
