The Square Root Of Disappointment

Unlike the elegant divisibility rules for 2, 3, or 5, checking for divisibility by 7 feels like filing your taxes with a broken calculator. That convoluted "take the last digit, double it, subtract from the rest" trick is mathematical torture that even calculators were invented to avoid. And just like Bernie's persistent campaign messages, this rule keeps showing up in math classes despite everyone silently agreeing we'd rather just do the long division. Pro tip: if you've spent more than 10 seconds applying the rule, you could have just divided the damn number already.

The calculus monster looks terrifying when you first see those scary derivatives and differentials (DY/DX, ∫(X)DX) looming over you! But the bottom panel reveals the truth - once you actually start learning the concepts instead of just seeing them in advanced textbooks, they're way less intimidating. That moment when mathematical notation transforms from "cryptic alien language" to "oh, that's just the slope formula with extra steps" is pure educational comedy gold! The fear was all in your head!

Oh, sweet mathematical optimism! The top equation represents 2020 as a simple integral of 1/x⁵, which is already pretty terrible since it approaches infinity as x approaches zero. But 2021? That's the same nightmare with "+1" in the denominator—a pathetic attempt to make the function marginally less catastrophic. It's like thinking a life preserver will help when you're being sucked into a black hole. Spoiler alert: when your disaster is measured in powers of x⁵, adding 1 is just mathematical thoughts and prayers.

Ever notice how your rectangular blanket transforms into a non-Euclidean manifold at precisely 3 AM? That's when your cozy cotton sheet decides to obey the laws of topological mathematics instead of common sense. What should be a simple rectangle becomes a hyperbolic paraboloid with no discernible long edge—just saddle points and mathematical chaos. It's like your blanket is secretly conducting advanced calculus experiments while you're half-conscious. The fourth dimension opens up specifically to mess with your sleep schedule!

That moment when you realize video game developers put more complex math into Pokéball animations than most people use in their entire careers. While you were struggling with algebra, Nintendo engineers were deriving equations to perfect the "shakey shakey" of a virtual ball. The best part? Some poor programmer probably spent weeks optimizing this formula only for players to mash the A button impatiently through the whole animation. Next time someone asks "when will I use math in real life?" just show them this—proof that differential equations are essential for... *checks notes*... digital monster-capturing aesthetics.

That moment when you realize the matrix determinant equals 8 because the zeros multiply to give you... zero. Revolutionary stuff. Next stop: Fields Medal for proving that empty space is, in fact, still empty. My colleagues in the department are going to lose their minds over this groundbreaking discovery that multiplication works exactly as it has for the past several millennia.
