Formally, a Boolean algebra is a mathematical system consisting of a set of elements, B={0,1}, together with two binary operations, (denoted by the symbols + and •) There is also a unary operator ′.

I understand the laws and the operations ( and, or, not). I just need help understanding this unary ' thing.

For instance : Z=( A ' • B ' ) '+ C ' ) '

Also : Z = ( A • B ' ) ' + B ) • C

- I thought it was the "not" symbol until i saw these. Please help me understand.
