Re: Order of operations (fwd)

I don't think the point is that we should teach students different orders of operations but to help them understand why we have such rules and why we use the one we do today.
I don't understand why going right to left will eliminate the need for parentheses. How would (x+2)(y+3) be done in such a rule?
