This is math humor at its most ancient! The meme brilliantly pairs the sigma (Σ) symbol used for summation in mathematics with the step pyramid of Djoser, then contrasts it with the integral symbol (∫) and the Great Pyramid of Giza. It's a perfect visual pun showing how ancient Egyptian architecture evolved from "discrete summation" (step-by-step layers) to "continuous integration" (smooth sides)! Imhotep, the genius architect behind the first pyramid, would totally appreciate this calculus joke 4,600 years later. From chunky steps to sleek slopes - that's what I call mathematical evolution!
