This is a big problem. If you at the very least have an elementary
calculus background, I would recommend you try to read Richard W.
Hamming's book "Digital Filters" (ISBN: 0132128950). It covers all of
the basics you need to know about digital signal processing and it's
written in a more friendly style than most math books I've seen. It
explains what the discrete Fourier transform actually computes (I'm
not sure if this is entirely clear to you...), how to use windowing
functions, what is meant by frequency aliasing, what negative
frequencies are, and why it's not such a good idea to zero pad the
data you feed into your FFT routine, among other things. Find it in a
library somewhere.
