We have arranged an array of numbers below. What you have to do is use any kind of mathematical symbol you know excluding any symbol that contains a number like cube root. You can use any amount of symbols but you have to come up with a valid equation for all of them.

0 0 0 = 6

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

(0! + 0! + 0!)! = 6

(1 + 1 + 1)! = 6

2 + 2 + 2 = 6

3 x 3 - 3 = 6

√4 + √4 + √4 = 6

5 + 5/5 = 6

6 + 6 - 6 = 6

7 - 7/7 = 6

8 - √√(8 + 8) = 6

√(9 x 9) - √9 = 6
