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

(1+1+1)!

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

That's perfectly acceptable. It's just 3!.  Reply With Quote

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

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

! is the 'factoral' sign

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

(1+1+1)! = 3! = 3x2x1 = 6  Reply With Quote

2! = 2 x 1

4! = 4 x 3 x 2 x 1

Someone wasn't paying attention in 'maths'.  Reply With Quote
