I am a person bad at math, but as I am growing older each year (I am already 22) I am trying to see the importance of being good at numbers. I have finished college while paying little attention to my math subjects (I did something in IT). I had the notion that it was not really important but I realized that I wanted to learn new stuff which involves a lot of numbers in a major way (like mechanical engineering and robotics). And when I try to see some formulas and stuff, it seems like I am looking at a language out of this world and don't understand a thing about it.

I was wondering if you could give me some references or suggestion on how can I get myself back on track with my maths.
