1/infinity isn't zero. It's an infinitesimal, but it isn't zero . Which is why 0.99999 doesn't equal 1. Just infinitely close

Wrong. $1/\omega$ is an infinitesimal. $\omega \neq \infty$.

$\frac{1}{\omega}$ is an infinitesimal.
$\frac{1}{\infty} = 0$ .
$\omega \neq \infty$ . They are different things.

What he presumably meant is that infinitesimals don't exist in R. 0.999... denotes a real number, and that real number is the same real number denoted by 1, 3 - 2, 1.0000, (5+1)/6, etc.

Posted the infinitesimal comment. I watched a numberphiles video like 4 years ago about infinitesimals and have zero idea what these equations even mean or what is being talked about lol
