Answer 2

Let's solve this step by step:

675 + 25 - 5 * 7 = 675 + 25 - 35 = 665

(7 + 21) : 7 + 100 = 28 : 7 + 100 = 4 + 100 = 104

(600 - 3 * 4) - 39 = 600 - 12 - 39 = 549

100 - (20 : 5 + 16) = 100 - (4 + 16) = 80

4 * (100 - 93) - 16 = 4 * 7 - 16 = 8

(237 - 217) : (312 - 308) = 20 : 4 = 5

Therefore, the final answer is 5.
