You should put such mathematical signs between 1 1 1 so that 1 1 1 = 6

any idea

(1+1+1)!

I don't know if it's OK because the factorial sign is after and not between.

That's perfectly acceptable. It's just 3!.

4. Perhaps we should write some three signs which are similar with S . / and get the word SiX SIX=6

5. I think we're talking about maths here, not doodling :P.

N.B.: to doodle (int. v.) - to draw casually, often absent-mindedly.

6. what does the word mean?

no - I means math, not doodling...

7. Mathematics. "Математик", isn't it?

8. Mathema...and then tics? That you did say?
Is it vegetable or mineral?

I'm kidding you - oh come on you dont think I really have no idea what the math is?

9. Heh, you just might not have known the short form "maths".

10. No actually I know.
I forgot the letter s

any idea
Must I use all digits?
Can I use: +, -, x, / (divided by) several times?
Can I use square root?

Friendy has already given the answer (1+1+1)!

! is the 'factoral' sign

2! = 2x1
3! = 3x2x1
4! = 4x3x2x1

(1+1+1)! = 3! = 3x2x1 = 6

3! = 3 x 2 x 1
4! = 4 x 3 x 2 x 1

Someone wasn't paying attention in 'maths'.
