WM submitted this idea :Cardinality is nonsense. Set differences are established by their elements. ℕ_0 differs from ℕ by one element. Do you want to contradict? Don't make a fool of yourself!Therefore ℕ_0 as a proper superset of ℕ has one elements more than ℕ. Infinity does not make them equal.Yes it does, cardinal arithmetic works differently in the two realms of finite and infinite.
