You just need -infinity=infinity (think a number circle instead of a number line), and you're good. It's 0/0 where the real crimes begin. permalink fedilink source parent hideshow 4 child comments replies: [–] blind3rdeye@lemm.ee 10 points 2 years ago (1 child) Yep. ∞ is infinitely big in the same way that 0 is infinitely small. -0 = 0 and -∞ = ∞. Opposite ends of the circle. (Or the Riemann sphere if you like complex numbers.) permalink fedilink source parent hideshow 2 child comments replies: [–] raspberriesareyummy@lemmy.world 7 points 2 years ago* (3 children) While this Riemann sphere seems like a useful concept, -∞ = ∞ is an observation that doesn't seem to hold true outside this spherical model of complex numbers. Just add ∞ to the both sides, and you end up with 0 = ∞ + ∞ which is most certainly not true. permalink fedilink source parent hideshow 6 child comments replies: [–] cows_are_underrated@feddit.de 4 points 2 years ago (1 child) 0 = ∞ + ∞ which is most certainly not true. This is only true if both infinite are the same, but one is negative.
