Answer 2

Calculation:

To calculate the given expression: 8 + 7 - 9 + 5 + 6 - 8 + 13 - 5 + 4 + 14 - 6 + 2 + 5 + (16 - 8) + 7 + (15 - 9), we can follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Let's break down the calculation step by step:

1. Start with the parentheses: (16 - 8) = 8. 2. Replace the expression with the calculated value: 8 + 7 - 9 + 5 + 6 - 8 + 13 - 5 + 4 + 14 - 6 + 2 + 5 + 8 + 7 + (15 - 9). 3. Calculate the expression within the parentheses: (15 - 9) = 6. 4. Replace the expression with the calculated value: 8 + 7 - 9 + 5 + 6 - 8 + 13 - 5 + 4 + 14 - 6 + 2 + 5 + 8 + 7 + 6. 5. Perform the addition and subtraction operations from left to right:

8 + 7 = 15 15 - 9 = 6 6 + 5 = 11 11 - 8 = 3 3 + 13 = 16 16 - 5 = 11 11 + 4 = 15 15 + 14 = 29 29 - 6 = 23 23 + 2 = 25 25 + 5 = 30 30 + 8 = 38 38 + 7 = 45 45 + 6 = 51 51 + 6 = 57

Therefore, the final result of the expression 8 + 7 - 9 + 5 + 6 - 8 + 13 - 5 + 4 + 14 - 6 + 2 + 5 + (16 - 8) + 7 + (15 - 9) is 57.
