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 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.
is project euler a good site to brush up on my math
