Sigma-notation Memes

That intimidating Σ (capital sigma) notation that made you question your life choices in calculus? Yeah, it's literally just a for-loop. And that Π (capital pi) symbol that looked like a gateway to mathematical hell? Also a for-loop, but with multiplication instead of addition. The summation iterates from n=0 to 4, adding 3*n each time, while the product does the same from n=1 to 4, multiplying by 2*n. Once you realize mathematical notation is just fancy syntax for basic programming constructs, suddenly those textbooks become a lot less threatening. It's the same energy as discovering that "algorithm" is just a pretentious way of saying "recipe."

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.
