Answer 2

To solve the given expression step by step, follow the order of operations (PEMDAS/BODMAS):

P - Parentheses first E - Exponents (none in this case) MD - Multiplication and Division (from left to right) AS - Addition and Subtraction (from left to right)

Let's go through the steps:

1. 56 ÷ 8 + 42 × (42 - 39) - 3 × 4 + 24 ÷ 8

2. Start with the parentheses: 42 - 39 = 3

3. Replace the expression with the result: 56 ÷ 8 + 42 × 3 - 3 × 4 + 24 ÷ 8

4. Perform the division: 56 ÷ 8 = 7

5. Replace the expression with the result: 7 + 42 × 3 - 3 × 4 + 24 ÷ 8

6. Perform the multiplication: 42 × 3 = 126 3 × 4 = 12

7. Replace the expressions with the results: 7 + 126 - 12 + 24 ÷ 8

8. Perform the division: 24 ÷ 8 = 3

9. Replace the expression with the result: 7 + 126 - 12 + 3

10. Finally, perform the remaining additions and subtractions: 7 + 126 = 133 133 - 12 = 121 121 + 3 = 124

So, the final result of the expression is:

56 ÷ 8 + 42 × (42 - 39) - 3 × 4 + 24 ÷ 8 = 124
