if i had to guess theres some bug in your code, but as long as it works it works.
>So i thought i could get rid off M2 and M4 since it's the M5 that now handles the movement, but nope, if i remove them it doesn't work properly anymore. However with M1*M2*M3*M4*M5 it does
the goal of M3 is to rotate the figure about point A, and since that rotation matrix formula is for rotations about the origin, we have to first subtract A0 from all points (the M2 matrix) so that point A is at the origin. M4 and M5 are both translations so they can be done in one step (i suspect that your M5 matrix is compensating for some error in your M4 code).
also, dont be so hard on yourself, anon. most guys wouldve stuck with your "good nuff" solution, but you decided to struggle through learning a new topic to do it the right way. that puts you ahead of 95% of people.

dont be so hard on yourself, anon, its something that takes practice
