This little guy craves the light of knowledge and wants to know why 0.999... = 1. He wants rigour, but he does accept proofs starting with any sort of premise.

Enlighten him.

And doesn’t this mean 0.99 approaches 1

A real number can't be approaching anything. It is not a function or any other sort of object that can be said to be approaching anything.

No. 0.99 is 0.9+0.09. The proof I gave shows that 0.99999999999999999999999999999999999(...) is equal to 1.
