Why aleph‑null + aleph‑null = aleph‑null (The Math of Infinity)
Aleph-Null: The Smallest Infinity Aleph-null (ℵ₀) is a cardinal number in set theory that represents the cardinality, or size, of the set of natural numbers {1, 2, 3, …}. It is the first transfinite cardinal number and is used to describe the size of infinite sets. Arithmetic with Aleph-Null Aleph-null is closed under addition, multiplication, read more
