Hi. I just found this site, and I want to find very easy problems. The only one that I have solved is the first, and probably the easiest one, number 1000.

Hope someone can help me!

In the problemset the rightmost column denotes the number of people who solved this problem. If this number is big enough, then the problem is easy with high probability. Or you can try to start solving problems from the school contests, they are usually a bit easier.
