Which books are recommended for learning math from the ground up and review the basics – from middle school to graduate school math?

I am about to finish my masters of science in computer science and I can use and understand complex math, but I feel like my basics are quite poor.

**Answer**

Get Mathematics: Its Content, Methods and Meaning by Kolmogorov et al. This is a readable summary by the top Soviet mathematicians, and as the Soviets had no copyright it is incredibly inexpensive. If you have mastered this, you are pretty well prepared for anything.
