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!
