Hi, I am looking for a book or folder containing math assignments. Mainly I'm looking for assignments in mental problem solving.
A book full of basic math (addition, subtraction, multiplication and division) with increasing difficulty would be appreciated. All I'm really hoping for is some help increasing the speed of my general problem solving.
I've already googled it a little bit, but with no success. I really would appreciate some help.
