now converting that to pep/8 is killing me, I know how to do the basic stro commands for a,b,c but doing the arithmatic shift left and shift right for the algebra equation is what I'm stuck on.

if anybody can give me a hand that would be awesome

program "works" but if I put a negative value for B then it gives me the wrong value
