Notation Memes

The eternal war between math and code in one factorial joke! In programming, 2! is just a very excited 2 (or a boolean NOT applied twice, returning the original value). But for mathematicians, 2! is factorial notation meaning 2×1=2. The programmer's horrified "No" versus the mathematician's smug "Yes" perfectly captures why we can never have nice things in cross-disciplinary meetings. And why commenting your code matters—unless you enjoy watching your math friends have aneurysms during code reviews.

The moment when you realize those intimidating Greek symbols from calculus are just fancy for-loops in disguise! The Σ (sigma) notation is literally just a sum = 0 followed by a for-loop that adds stuff up. And that scary Π (pi) symbol? Just a prod = 1 with a for-loop that multiplies things together. Computer science majors smugly realizing they've been doing advanced math all along without the pretentious notation. Take that, pure mathematicians!
