I'm honestly not very fond of math, but have one way help me remember how to solve fractions easier that I learned in Fitfth Grade. The little mover man who has his baseball cap! It's the funniest thing in the world, but it helps me more than anything else. Personallity, the distributive property probably helps me the most, but I've never really used it in math, I don't use the others either. I can be so stubborn that I forget anything like that that's useful for me. I just do the problem as is most of the time.
