Hi everyone,

I know that this is not a good question to post on Codeforces, but since we all know that a good mathematical background does greatly improve our programming skills, I wonder whether or not there are any good books in Maths to learn, and of course it would be even better if they could be similar to Introduction to Algorithms or Competitive Programming.

I know that many great coders on Codeforces are also great mathematicians, such as the legendary Xellos. Could you share your secret and books to learn Maths with us?

Thank you.
