"Discrete Mathematics"

as i'm currently studying for my discrete math final i find myself wondering once again what's the application of any of this in programming?

here are some keywords to give you a quick refresher: truth tables, logical equivalences, propositional logic, predicate logic, relations vs. functions, equivalence relations, proof by contraposition/contradiction/induction

give me some god damn motivation

Sorry, but I'm the least educated (never attended even a school) here and have lowest salary ($0). So facts speak against me.

And I hate Jews not because Jews evil, but because I'm jealous at Jewish success. I.e. I'm not some moralfag, who believes usury is bad. I just want to do usury myself, but niche is already occupied.
