Answer 2

To solve the given expression using the order of operations, we need to perform the operations in the following order:

1. Parentheses (including any nested parentheses)
2. Exponents (if any)
3. Multiplication and division (from left to right)
4. Addition and subtraction (from left to right)

Let's break down the expression step by step:

(7 · 8 – 14 : 14) + (7 · 4 + 12 : 6) – 10 : 5 + 63 : 9

Step 1: Parentheses (7 · 8 – 14 : 14) + (7 · 4 + 12 : 6) – 10 : 5 + 63 : 9 (56 - 14 : 14) + (28 + 12 : 6) – 10 : 5 + 63 : 9

Step 2: Division (56 - 1) + (28 + 2) – 10 : 5 + 7 : 9 55 + 30 – 10 : 5 + 7 : 9

Step 3: Division 55 + 30 – 2 + 7 : 9 55 + 30 – 2 + 0.777777778

Step 4: Addition and subtraction 85 – 2 + 0.777777778 82 + 0.777777778 82.777777778

Therefore, the value of the given expression is approximately 82.777777778.
