Escalator Memes

This meme perfectly captures the eternal mathematical debate: summation vs. integration! On the left, we have Sigma (Σ), represented by a stepped escalator with distinct, countable steps—just like how summation adds discrete values. On the right, the integral symbol (∫) is represented by a smooth escalator, showing the continuous nature of integration where we're calculating area under a curve. Every mathematician has a preference, but we all know which one is easier on exam day. Discrete steps or smooth sailing? Your calculus professor is judging your choice right now.
