simplification?
aa
_
a  a
_
b
not sure if that makes sense like that but im not entirely sure how to write it, basically a take away a over a take away a over b, simplified.
Would I be right to make the last part
a a
__
1 b
so it turns into 1b because the top parts cancel each other out, so I'm left with aa
_
1b?
Or is that completely on the wrong track?

Did you mean ?

Nope. Hmm, how to explain it.

_
q  y

b
a=z=q=y, but hopefully it gives more clarification, its a minus z over q minus y over b.
edit: nope, cant get the underscores to stay spaced out how id like ><

, well if this is the case let's simplify it:

There isn't any possible way to simplify this, if I apply this to your question:
,
It can't be simplified any further.
In case you have the thing that Defunkt wrote:
not possible because we divide by
