June 2016 Brain Teaser Solution

Q: The following equations are incorrect.  Fix them using these rules.
No other numbers can be written.
No inequality symbols can be used like a “greater than” sign, a “less than” sign or “not equal to” sign.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 =6There can be multiple answers for one equation.

Hint: you can use ! and square roots
A:
(1+1+1)! = 3! = 3 x 2 x 1 = 6
2 + 2 + 2 = 6
3 x 3 – 3 = 6
4 + 4/sqrt(4) = 6
5 + 5/5 = 6
6 + 6 – 6 = 6
7 – 7/7 = 6
8 – sqrt(sqrt(8 + 8) = 2
9/sqrt(9)  + sqrt(9) = 6
(0! + 0! +0!)! = 6
