 XP Math - Forums Maths Query?

 08-01-2007 #1 stepbeanie Guest   Posts: n/a 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
