To add the operation signs and parentheses in order to make the equation 6 5 9 2 = 77 true, we can use the following steps:

1. Start with the given numbers: 6, 5, 9, 2.
2. We need to insert operation signs and parentheses to form a valid equation. Since we only have addition, subtraction, multiplication, and division at our disposal, we should explore different combinations to reach the target of 77.
3. Let's try a few possibilities:

a) (6 + 5) * (9 - 2) = 11 * 7 = 77

b) 6 + 5 + 9 - 2 = 11 + 9 - 2 = 20 - 2 = 18

c) 6 + 5 * 9 - 2 = 6 + 45 - 2 = 51 - 2 = 49

d) 6 * (5 + 9) - 2 = 6 * 14 - 2 = 84 - 2 = 82

4. After trying different combinations, we find that option a) works: (6 + 5) * (9 - 2) = 11 * 7 = 77.

Therefore, the equation with the added operation signs and parentheses to make 6 5 9 2 = 77 true is (6 + 5) * (9 - 2) = 77.
