Discrete mathematics Memes

This is a classic case of someone trying to apply mathematical set theory to social concepts without understanding how logical implications actually work! The notation in the title (A ⊇ B ⇒ A ⊆ B) is mathematically incorrect - if A contains B (superset), it doesn't imply that A is contained in B (subset). That's like saying "if all squares are rectangles, then all rectangles are squares" - which is demonstrably false! The tweet confuses subset relationships with categorical statements. In set theory, "trans women are women" would be expressed as "trans women ⊆ women" (trans women are a subset of women), but that doesn't logically imply the reverse statement "women ⊆ trans women" (all women are trans women). The person clearly slept through their discrete mathematics class and now thinks they've made some profound logical discovery. Next time, bring coffee to those 8 AM math lectures!

The mathematical induction joke that only nerds will appreciate! The top password shows just the induction step (P(n) => P(n+1)), which any cybersecurity expert would rate as pathetically weak. But the bottom password? It includes the base case P(1) and all steps up to P(n) before proving P(n+1). That's a mathematically complete and therefore strong password! Hackers would need a PhD in discrete mathematics just to understand what they're trying to crack. Security through mathematical rigor—finally a use for those proof techniques they tortured us with in college!

The internal screaming of every math major when someone makes a fundamentally incorrect statement about numbers! In discrete mathematics, zero is absolutely an even number because it satisfies the definition perfectly: any integer divisible by 2 with no remainder. Since 0 = 2 × 0, it fits the criteria flawlessly. That moment when your basic math knowledge transforms casual conversations into mental torture sessions. You want to correct them, but you'll sound like a pedantic nightmare. The struggle is real for anyone who's ventured beyond arithmetic into the beautiful, maddening world of mathematical rigor!

The mathematical world collides with feline curiosity in this masterpiece. The pigeonhole principle states that if you have n pigeons but fewer than n holes, at least one hole must contain multiple pigeons. Similarly, if you have n+1 cats trying to fit into n boxes, you're going to have a problem—or in this case, a very confused cat face peering directly into your soul. The cat's expression perfectly captures the existential crisis of being the n+1 entity with nowhere to go. This is what happens when discrete mathematics escapes the textbook and manifests in your living room at 3 AM.
