CS210 – Discrete Mathematics. Hands down the best course I have ever taken. I will argue my case from three different perspectives.

Discrete Mathematics as a Mathematics course

a.k.a Why Formal Math is good too, but Discrete Math is better.

I took both Discrete Mathematics and Introduction to Formal Mathematics in the same semester. I found Discrete Mathematics to be better. Why? It covers almost everything one learns in a formal mathematics course *plus more exciting stuff!* Formal mathematics covered proof-writing, set theory, cardinality, equivalence relations, functions and (very very) introductory group theory. Discrete Mathematics covered all of this except for the group theory part. However, it also covered introductory number theory, RSA Encryption (we missed that part, though. Due to cancellation of the last class), principles of counting and (the best and most exciting part) **graph theory**.

Discrete Mathematics as a Computer Science course

a.k.a Mathematics makes code fast and pretty.

Every Computer Scientist on the planet should take a course on discrete mathematics. It gives one the mathematical maturity needed for algorithm design, automata theory, data structures, computational complexity etc. On top of that, it helps one become a better programmer. It teaches one a *way of thinking* that enables one to write more efficient and, indeed, more beautiful code.

Discrete Mathematics as a Liberal Arts course

a.k.a One can’t argue with a sound mathematical proof

“Liberal arts and math? Lol, who is this nerd trying to kid.” I’m serious, though. To start with, Discrete Mathematics teaches *logic*. What’s better? It teaches *quantified* logic and proof writing. This helps one make better arguments and (more importantly) accept only claims backed with rational arguments, which helps one understand the world better.
