I’m doing computer science at uni and we just came across binary numbers addition (easy), subtraction (weird), multiplication (easy) and division (dunno) does anyone know of a web site which explains this to you? I googled it and I got a mixed bag of results some good some bad but none explain subtraction that well.

Cheers people 🙂
