Is this even possible? For example:

(a-1)/b --> ((a/1)*(1/b))-(1/b)

I have found I am able to do this with a lot of algebraic expressions. However, if a + or - exists in a denominator, I don't seem to be able to break it out. For example:

a/(b-1)

The best I can do is: (a/1)*(1/(b-1))

Just fyi, right now I am not seeking to solve for log, exp, etc, just +-/* operators...

Thanks!
