Math major tip


Thanks to Anderson da Silva for this submission, who has this to add:

I just saw this on the internet and had the urge to come here and share it.
I know Pi is always around but I really never though it would be useful when paying a bill.
Well, what a nice surprise.

P.S. As I said, I saw this on the internet. If you know the source, please feel free to spread the gospel
