Is ∞ a Number?

No — ∞ is a symbol representing unbounded growth, not a number in the usual sense

Explanation

\(\infty\) is not a number in standard mathematics. It is a symbol — first proposed by the mathematician John Wallis (1616–1703) — representing the idea of quantities growing beyond any bound. Not all algebraic operations are defined for \(\infty\). Saying \(1/n = 0\) when \(n = \infty\) is wrong precisely because \(\infty\) cannot be substituted as a number.
