Hi 
, I'm Franco, I peek this forum occasionally! It's awesome to check all the things I don't know 
Anyway! I'm a computer science student, so I usually do maths, actually I'm reading "Discrete Mathematics and its Applications".
Mmm, I would love to hear why you are studying maths! researchers, professors, just an annoying hobbie?
Cheers!

I get it doing this
Finally! This is the way you make the cancelling? all that in your head??
Well, now i put here this resource

(the graph is really cool)

Hi Bob! I'm feedbacking you really late! Sorry for that. First, I have to say thanks for the answer and your time.
Yes, I love this method for the reason that you said!
Now.. I can't see the transition here..
IF you like to explain it to me. I don't know if i'm missing a property or something like that. You write down that you was using cancelling.
Really pissed me off that I can't see it!
Mr, you have a degree on maths, or studying, or hobby?
I really appreciate you're help. Thanks

First of all, I was looking for proofs for this:
I check it by induction, but I see on other topic of the forum this one:
I didn't get it from the 3rd to 4th line.
In the right side use distribution, but on the left
Can anybody 'expand it' for me?
Ps: It's my first post so if there is something wrong, just tell me. And sorry for my bad english.
