I found my rating always fall down if there are a lot of math(specially, number theory). Where can I find those problems about difficulty div2 D~E?

I think you can try solving some problems of fair difficulty on project Euler and go step by step till you reach some challenging maths problems. I strongly believe it will enhance your mathematical thinking and analysis. Other easy way around is to filter CF problems by Tag maths and number theory and choose rating ~1800-2000 I have think that it will be the difficulty you seek. Best Wishes

I practiced for that solving div1C-E when I was cyan. It took a few days per problem but it was worth it ;)

Might be good to practice a bit on topcoder (Div 1 Easy and Medium) and atcoder (AGC A-C). Their problems are less implementation and more observation + math. I believe topcoder has a tag system as well, so you can filter to get the ones you want.
