Oh look, it's Euler's identity having an identity crisis! The top panel shows the classic formula (eiπ + 1 = 0) which mathematicians drool over at parties. But the bottom panel reveals the elegant rearrangement (eiπ = -1) where our bear friend is suddenly wearing a tuxedo.
It's literally the same equation just solved for a different variable, but mathematicians act like the bottom version is attending the Met Gala while the top one shops at Walmart. Pure mathematical snobbery! Next they'll be arguing about whether to write 0.5 or ½ on their dating profiles.
