Fuck, if I have to be a pedant, I'd better go all the way: well, they might be, but
1) they don't use * as the multiplication symbol, but ~ "x".
2) they don't multiply words and numbers... Repeating a string this way is something programmers do.
I don't think anyone will have difficulty grasping that 'Simplify Simplify Simplify' and 'Simplify x 3' can be considered equal.
