You got math(s) in high school? You were lucky! (obligatory MP ref:

Actually I've found this to be generally true - algebra, linear algebra 
(vectors & matrices) and complex numbers / trigonometry (all of which I 
actually got in high school despite the above) will give you 95% of what 
you need to handle DSP. Calculus rarely comes into the picture.

The trick is knowing when to look away from the integrals & summations 
that the academics are always throwing around. Once you've seen enough 
of them you start to ignore the details and recognize the entire 
equation as a convolution, dot product, etc. Admittedly it took me a 
while to get to that point...
