The mathematical irony here is delicious! While the "normal" frog accepts 2+2=4 as basic arithmetic, mathematicians know this is actually a complex theorem derived from Peano axioms. Pure mathematicians would demand rigorous proof for even the most "obvious" statements. Meanwhile, the right side parodies the "source?" demand with excessive skepticism, but in higher mathematics, questioning foundations is literally the job description. Mathematicians spend careers examining whether 2+2 truly equals 4 in all number systems and abstract algebras. The real punchline? Both sides would drive pure mathematicians crazy - one for accepting without proof, the other for rejecting proof methodology entirely. Gödel's incompleteness theorems are cackling somewhere!
