I am terrible at math. I use it constantly. I "get it" that algebra can use some values to find unknown values. I "get it" that geometry can be useful to find square footage. I failed 2nd year algebra/calculus twice before I got a passing grade in college. This cut me right off in fields I was interested in, such as "fighter pilot", "astronaut" "spy-satellite photo-interpreter" and so on. Now I work as a photographer, and I use ratios, square footage, the inverse square law, and many of the things I had trouble with in math in college, I can use the "calculator" function in Google... have you seen that lately btw? I would have loved to work on spy sat photos for the CIA but instead I shoot photos of sexy women. dammit.
