I am a self-taught programmer in my 30s (with an undergrad degree in humanities) now back in school. One of the main reasons I decided to return to school rather than continuing to program on the job was that I wanted to improve my math skills. When you say you know nothing about math, does that mean you have no Calculus? That was where I was starting. To prepare for Calculus, get solid in algebra and trig. Then do single-variable Calculus (Calc 1 & 2). My recommendation would be to do linear algebra before multivariate calculus. You can do Calc 2 and Linear Algebra at the same time. If you have no Physics experience you might also consider studying it. Physics helps you learn by applying math concepts. Also, I think it is very good for teaching you to problem solve as an engineer.
