Ready for more accidental learning? ∞ is defined by the equation of k/0. ∞ is not a value, it's an idea. An idea of never-ending.

Say say we have k/∞. What we really have is k/k/0, a complex fraction. When dividing a complex fraction, you're basically same the same thing as this --→ (k/1) * (0/k) which comes out to 0. Hence the reason why k/∞ = 0

k * ∞ = ∞

k + ∞ = ∞

k - ∞ = ∞

k / ∞ = 0

Yes, the last one is zero. Since every single one of these posts is k/∞, then all these posts do not exist.
