(I never have been a A math student)I am having troube understanding, what the numbers in matrices respresent. Are they variblaes or just numbers, and how would I call those numbers, why, and when? They are pretty confusing mainly because I dont know what the numbers are there for. I am doing matrices mainly for OpenGL.

OpenGL will construct most matrices for you so you don''t need to know what goes where to use it. Rather you have to understand translation, rotation, scaling and projection. The main thing to remember is that functions such as glRotate, glScale and glTranslate modify the current matrix which makes everything cummulative until you call glLoadIdentity. You have plenty to learn without bogging yourself down at the start trying to learn every little detail about how each function does what it does. First learn how to use the functions that are available then worry about how they do what they do.
