Math for programming

To what level of math should I learn to be a good programmer?

I'm way too bad at math and I know it. I `studied' math at high school but never really cared about it. I managed to pass the math courses at college with common sense and acquired programmatic thinking. I struggle with basic algebra that I could've solved in high school with ease. This is not a good thing and I recognize that, but I haven't found a way to brush up my math skills without that ``millions of pages of proofs'' nonsense.

I'm still a better programmer than any of those `mathematician-turned-programmer' types, and I know that too.
