I found this site in my history and decided to check back on it
and I tried making an account but the email was in use!
And I remembered asking a question like a year ago.
Well, I'll be here trying to improve my math skills :3
What would you like to do about that? Close that account?
In mathematics, you don't understand things. You just get used to them.
I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.
