Computer engineers are the most greedy people!
YYY: In the sense?
A simple task: Vova has three apples, one of which he shared with Dima, how to know how many apples he has left?
YYY: Take one out of three.
xxx: And if Vova has three kilobytes of information and one of them he shared with Dima, how much is left?
YYY: Three is left.
How do you express it mathematically?
YYYYYYYYYY
XXX is here! You see how these greedy bastards learned to share without harming themselves.
