You have 3 digits, two blanks in between and a = result and you need to put necessary mathematical sign to achieve results which now is 6.

Plus+, minus-,divide/, multiply X, or whatever mathematical signs you know may be used.

1  1  1 = 6

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

Answers -

2 + 2 + 2 = 6

3 X 3 - 3 = 6

4  4  4 = 6  ( sq.root of 4 is 2. Add all the sq.roots )

(5 / 5) + 5 = 6

6 X 6 / 6 = 6

7  - ( 7/7) = 6

8  8  8 = 6  ( Cube root of 8 is 2. Add all cube roots )

9  9  9 = 6 ( Sq root of 9 is 3. multiply the first two sq.roots                     MINUS the last sq.root )

(1+1+1)! = 6  ( Factorial 3 i.e., 3! = 3 X 2 X 1 = 6 )
