Notation Memes

Look, that intimidating Sigma and Pi notation you avoided in college? Yeah, they're just fancy for-loops with better PR. Summation is literally sum += 3*n and Product is prod *= 2*n . That's it. Mathematicians really said "let's make simple iteration look like ancient Greek spellcasting" and then wondered why people have math anxiety. Meanwhile, your average dev writes these same operations daily without breaking a sweat. The real plot twist? Once you realize math notation is just verbose pseudocode written by people who peaked before computers existed, algorithms suddenly become way less scary. Your CS degree just demystified centuries of mathematical gatekeeping in one tweet.

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!
