Now here's a math puzzle. You must arrange the left side of the equation by adding mathematical expressions so that it equals 6. You cannot add any other numbers.

I'll give one example (the easiest) : 2 + 2 + 2 = 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

So we have to ue the numbers given? And can only use add, subtract, divide, and multiply?
