Unless you are doing something novel, not so much imo. I generally trust standard approaches and tools, I'm not trying to write my own encryption, right, or reinvent wheels. You can often get by with no real understanding of the underlying math, just what you put in, what you get out, and what that generally means. Lots of respect to you math geniuses who make it all possible. I'd rather play and prototype stuff than perfect and get into the nitty gritty. But math in programming is great for learning and understanding, it being actually applied.
