Answer 2

To simplify the given expression using the order of operations (PEMDAS), we should perform the following operations in order:

1. Calculate 14 ÷ 7, which equals 2.
2. Calculate 12 ÷ 6, which equals 2.
3. Calculate 7 * 8, which equals 56.
4. Add the result of step 1 to the product from step 3: 56 + 2 = 58.
5. Calculate 7 * 4, which equals 28.
6. Add the result of step 2 to the product from step 5: 28 + 2 = 30.
7. Calculate 10 ÷ 5, which equals 2.
8. Calculate 63 ÷ 9, which equals 7.
9. Add the result of step 7 to the quotient from step 8: 2 + 7 = 9.
10. Add the results of step 4 and step 6: 58 + 30 = 88.
11. Subtract the result of step 9 from the sum from step 10: 88 - 9 = 79.

Therefore, the value of the given expression is 79.
