Formerly known as Shack’s Math Problems
By Michael Shackleford, A.S.A.
Welcome to my site of math problems. Anyone with an appreciation of a good math problem should find something they like here, with problems ranging from basic math to differential equations. Each problem also comes with a difficulty rating from one to four stars. This is roughly a measure of how much time it took me to do the problem. Since your math background is likely different from mine your experience is likely to vary.
