Default Maths Query?

Does anyone know the solution to the following where you only have to use mathemaical symbols to solve the equations e.g. 2+2+2=6. I can get them all apart from 111=6 which I know has something to do with putting the 1's in brackets & is some sort of series known by a specific name if you know the name that would be even better. I'll post the answers later for the rest of them if anyone needs them. 111=6222=6 333=6 444=6 555=6 666=6 777=6 888=6 999=6 Many thanks

well... i got the same as kiamehr... kinda pointless me typin it out again... but i will give a quick explanation of the factorial function if you havnt come across it before, nothing too detailed.3!=3 x 2 x 1i.e. x! is the same as x(x-1)(x-2)(x-3)... so on until (x-[x-1])... which is the same as (1), where x is a positive integer.
