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

2 + 2 + 2 = 6

(1+1+1)! = 6

(3* 3)- 3 = 6

(4 + 4) - Sqrt (4) = 6

5 + (5/ 5) = 6

(6 + 6) - 6 = 6

7 - (7 / 7) = 6

figuring out the rest.... -_-

1. (1+1+1)!=6

2. 2+2+2=6

3. (3*3)-3=6

4. sqrt(4) + sqrt(4) + sqrt(4)=6

5. (5/5)+5=6

6. 6+6-6=6

7. 7-(7/7)=6

8. 3rdrt(8)+3rdrt(8)+3rdrt(8)=6

9. [sqrt(9)*sqrt(9)]-sqrt(9)=6

what is the function of the "!" operator used in answer

(1+1+1)!=6

is it not equal to operator?

In mathematics "!" means "factorial"...in programming languages it is often used to mean "not", so that may be where your confusion is coming in...also, I agree, in the way it was posted it looks like they are saying "NOT EQUAL"...but it should be written (1 + 1 + 1)! = 6...or even slightly more separated ((1 + 1 + 1)!) = 6

Basically n! means n * (n - 1) * (n - 2) * ... * 2 * 1

So, for example:

1! = 1 = 1

2! = 2 * 1 = 2

3! = 3 * 2 * 1 = 6

4! = 4 * 3 * 2 * 1 = 24

5! = 5 * 4 * 3 * 2 * 1 = 120

6! = 6 * 5 * 4 * 3 * 2 * 1 = 720

...etc...etc..

make sense?

So, the answer posted (1 + 1 + 1)! = 3! = 3 * 2 * 1 = 6...which is a correct/valid solution.

Hmm;

(1 + 1 + 1)! = 6

2 + 2 + 2 = 6

(3 + 3 - 3)! = 6

sqrt4 + sqrt4 + sqrt4 = 6

5 + (5/5) = 6

6 + 6 - 6 = 6

7 - (7/7) = 6

3rt(8) + 3rt(8) + 3rt(8) = 6

(sqrt9 + sqrt9 - sqrt9)! = 6
