I have just started getting into to C++ programming and was reading the tutorial on this website.

When I got to the part about boolean algebra i got stuck

This came straight from Wikipedia.

Introduction to Boolean algebra - Wikipedia, the free encyclopedia

In summary the three basic Boolean operations can be defined arithmetically as follows.

x∧y = xy

x∨y = x + y - xy

¬x = 1 - x
