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.
