Project Euler is great as a programming problem when trying to improve your solutions for speed. Also, as someone who has not touched fundamental maths in 5 years it was also a good refresher; having to think about prime numbers etc again. A good tip I have found is to use a language that can nicely manipulate longs saving you much overhead, I chose Python because it also has some nice maths libraries.
