Calculation of Expressions

Let's calculate the values of the given expressions step by step:

1. Expression 1: 45 + 27 ÷ 3 - 12

To solve this expression, we need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

45 + 27 ÷ 3 - 12 = 45 + (27 ÷ 3) - 12 = 45 + 9 - 12 = 54 - 12 = 42.

2. Expression 2: 90 - 36 ÷ 3 - 2 × 2

Again, we follow the order of operations.

90 - 36 ÷ 3 - 2 × 2 = 90 - (36 ÷ 3) - (2 × 2) = 90 - 12 - 4 = 74.

3. Expression 3: 84 ÷ 4 + 3 + 2

Following the order of operations:

84 ÷ 4 + 3 + 2 = (84 ÷ 4) + 3 + 2 = 21 + 3 + 2 = 26.

4. Expression 4: 100 - 10 × 9 - 8

Applying the order of operations:

100 - 10 × 9 - 8 = 100 - (10 × 9) - 8 = 100 - 90 - 8 = 2.

5. Expression 5: 17 + 15 × 3 × 0

Following the order of operations:

17 + 15 × 3 × 0 = 17 + (15 × 3 × 0) = 17 + 0 = 17.

6. Expression 6: 5 × 5 + 75 ÷ 5

Applying the order of operations:

5 × 5 + 75 ÷ 5 = (5 × 5) + (75 ÷ 5) = 25 + 15 = 40.

7. Expression 7: 17 × 3 + 2 × 10

Following the order of operations:

17 × 3 + 2 × 10 = (17 × 3) + (2 × 10) = 51 + 20 = 71.

8. Expression 8: 80 - 5 × 2 ÷ 10

Applying the order of operations:

80 - 5 × 2 ÷ 10 = 80 - (5 × 2 ÷ 10) = 80 - (10 ÷ 10) = 80 - 1 = 79.

9. Expression 9: 72 ÷ 6 + 6 × 5

Following the order of operations:

72 ÷ 6 + 6 × 5 = (72 ÷ 6) + (6 × 5) = 12 + 30 = 42.

Changing the Order of Operations with Parentheses

Now, let's change the order of operations using parentheses and calculate the values of the resulting expressions:

1. Expression 1: (45 + 27) ÷ (3 - 12)

Applying the order of operations:

(45 + 27) ÷ (3 - 12) = 72 ÷ (-9) = -8.

2. Expression 2: 45 + (27 ÷ (3 - 12))

Following the order of operations:

45 + (27 ÷ (3 - 12)) = 45 + (27 ÷ (-9)) = 45 + (-3) = 42.

3. Expression 3: (84 ÷ 4) + (3 + 2)

Applying the order of operations:

(84 ÷ 4) + (3 + 2) = 21 + 5 = 26.

4. Expression 4: 100 - (10 × (9 - 8))

Following the order of operations:

100 - (10 × (9 - 8)) = 100 - (10 × 1) = 100 - 10 = 90.

5. Expression 5: (17 + 15) × (3 × 0)

Applying the order of operations:

(17 + 15) × (3 × 0) = 32 × 0 = 0.

6. Expression 6: 5 × (5 + (75 ÷ 5))

Following the order of operations:

5 × (5 + (75 ÷ 5)) = 5 × (5 + 15) = 5 × 20 = 100.

7. Expression 7: (17 × 3) + (2 × 10)

Applying the order of operations:

(17 × 3) + (2 × 10) = 51 + 20 = 71.

8. Expression 8: 80 - (5 × 2) ÷ 10

Following the order of operations:

80 - (5 × 2) ÷ 10 = 80 - 10 ÷ 10 = 80 - 1 = 79.

9. Expression 9: (72 ÷ 6) + (6 × 5)

Applying the order of operations:

(72 ÷ 6) + (6 × 5) = 12 + 30 = 42.

I hope this helps! Let me know if you have any further questions.
