I solved about 270 problems several years ago, had fun doing it, mostly in python, but I reached a point where I just didn’t have the math theory chops to continue. I visit the site every now and then, try a few new problems, but without success. Some problems I can get started but seem to run into a brick wall. Others, I don’t even know how to approach the problem. All in all, however, it’s a great site to learn more about math.
