Answer 1

Given,

2 + 2 + 2 = 6

3 3 3 = 6

4 4 4 = 6

5 5 5 = 6

6 6 6 = 6

7 7 7 = 6

8 8 8 = 6

9 9 9 = 6

To find,

Use any of mathematical signs wherever you need to solve the above equations.

Solution,

The above equations can we written as the following

(3 × 3) - 3 = 6

(4 + 4) - (√4) = 6

(5 ÷ 5) + 5 = 6

(6 × 6) / 6 = 6

7 - (7 / 7) = 6

8 - √(√8 + 8) = 6

(√9 × 9) - √9 = 6

Hence, these are the mathematical signs required to solve the given equations.
