FAO CCNA students

I'm currently coming to the end of the first semester. However there is one thing that I just can't get... subnet masks =/

I find the cisco course material really user unfriendly and have looked at various web guides to no avail.

I would be most grateful if someone could post a guide about them and applying them, or a website that they used when studying them.

Thanks

NiCkNaMe, in your guide you use the term

"To establish how many bits you want to borrow, use the formula 2^(b) -2 (where b = borrowed bits)"

what does 2^ mean?

2 to the power of, ie if b=4 then 2^4 - 2 = 14

Ermmm... ok =/

2^4 = 2x2x2x2 = 16

2^4 = 16

2^4-2 = 16-2 = 14

Ahhhh... much better. Thanks
