how can I name my variables in a readable way?

Last time I posted a problem with my code, the comment that stood out to me was that my variables need better names. I take this into account in my new code. But I think I'm taking it to an extreme. I have multiple variables named things like "1st_number" and "2nd_number". But that seems like it would make the code unreadable in a way too. what's a good way to make my variables descriptive in a good way?<br><br>you can show me bad code examples if you'd like. Even short examples would be good.
