The goal is to make all of the above equations true by adding mathematical symbols.

The rules are:

You can use as many mathematical symbols as you want for each equation
You are not allowed to use letters such as “cos”.
You are not allowed to add digits of any kind (like raising a value)
The result has to be exactly 6 ( not 6.0000000000000001 or 5.999999999999999 )
Square root is allowed
You are not allowed to change “=” to “/=” (not equal to) or manipulate the result in any way
Ceil and floor functions are not allowed (for those familiar with programming)

I want to point out that all of these have multiple solutions and there are no tricks involved, just math!

2. 2 + 2 +2 = 6
3. 3 - 3 + 3! = 6 ( 3 factorial = 6 )
4. 4! - (4^2) - ( sqrt4) = 6 (24 - 16 - 2 )
5. (5 C 5) + 5 = 6 ( 5 combination 5 = 1 )
6. 6 - 6 + 6 = 6
7. 7 - (7C7) = 6 ( 7 combination 7 = 1 )
For
3/ means cube root
2/ means square root
8. (3/ (eight)) + (3/(eight )) + (3/(eight )) = 6 ( cube root of 8 is 2, 2+2+2)
9. 9 - 3/( (9) * 2/ (9)) = 6 (square root of 9= 3, 3 * 9 ( the second 9) =27. Cube root of 27 = 3. Subtract from 9 to give 6.

Great! Some of them could have been done in a simpler way though, 3 3 3 for example.
Your 4 4 4 is wrong you introduced a number in addition to the symbol in 4^2.
