Answer 2

Calculation of Expressions

Let's solve the given expressions step by step:

1. 45 + 27 / 3 - 12 - First, we perform the division: 27 / 3 = 9 - Then, we perform the addition and subtraction: 45 + 9 - 12 = 42

2. 90 - 36 / 3 * 2 - First, we perform the division: 36 / 3 = 12 - Then, we perform the multiplication: 12 * 2 = 24 - Finally, we perform the subtraction: 90 - 24 = 66

3. 84 / 4 * 3 + 2 - First, we perform the division: 84 / 4 = 21 - Then, we perform the multiplication: 21 * 3 = 63 - Finally, we perform the addition: 63 + 2 = 65

4. 100 - 10 * 9 - 8 - First, we perform the multiplication: 10 * 9 = 90 - Then, we perform the subtraction: 100 - 90 = 10 - Finally, we perform the subtraction: 10 - 8 = 2

5. 17 + 15 * 3 * 0 - First, we perform the multiplication: 15 * 3 = 45 - Then, we perform the multiplication: 45 * 0 = 0 - Finally, we perform the addition: 17 + 0 = 17

6. 5 * 5 + 75 / 5 - First, we perform the multiplication: 5 * 5 = 25 - Then, we perform the division: 75 / 5 = 15 - Finally, we perform the addition: 25 + 15 = 40

7. 17 * 3 * 2 * 10 - First, we perform the multiplication: 17 * 3 = 51 - Then, we perform the multiplication: 51 * 2 = 102 - Finally, we perform the multiplication: 102 * 10 = 1020

8. 80 - 5 * 2 / 10 - First, we perform the multiplication: 5 * 2 = 10 - Then, we perform the division: 10 / 10 = 1 - Finally, we perform the subtraction: 80 - 1 = 79

9. 72 / 6 + 6 * 5 - First, we perform the division: 72 / 6 = 12 - Then, we perform the multiplication: 6 * 5 = 30 - Finally, we perform the addition: 12 + 30 = 42

Now, let's summarize the results:

- Expression 1: 45 + 27 / 3 - 12 = 42 - Expression 2: 90 - 36 / 3 * 2 = 66 - Expression 3: 84 / 4 * 3 + 2 = 65 - Expression 4: 100 - 10 * 9 - 8 = 2 - Expression 5: 17 + 15 * 3 * 0 = 17 - Expression 6: 5 * 5 + 75 / 5 = 40 - Expression 7: 17 * 3 * 2 * 10 = 1020 - Expression 8: 80 - 5 * 2 / 10 = 79 - Expression 9: 72 / 6 + 6 * 5 = 42
