Answer 3

Calculating the Expression

To calculate the given expression, we can follow the order of operations: parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

Given Expression: 80 + 2 * (3 + 6) * 2 * 5 + 6 * 2 + (6 + 8) / 2 + 6

Step-by-Step Calculation

1. First, we calculate the value inside the parentheses: - (3 + 6) = 9

2. Then, we calculate the multiplication within the parentheses: - 2 * 9 = 18

3. Next, we calculate the multiplication outside the parentheses: - 18 * 2 = 36

4. Now, we calculate the addition and multiplication in the given expression: - 80 + 36 * 5 + 6 * 2 + (6 + 8) / 2 + 6 - 80 + 180 + 12 + 7 + 6 - 285

Answer: The value of the given expression is 285.
