I am a nonmathy person. I would classify myself as mildly mathphobic, in fact, although I am mature enough to recognize that my competency is okay, just not by any means stellar, and I don't think there is an actual LD. I have never held a job that required more than extremely rudimentary math (most of my jobs have been in the writing and editing fields). For the sake of comparison, my math SAT score was in the mid-600s.

So, on that list...here is my assessment of what I use.

Found this list of topics taught in Algebra I:
�Representing numbers with variables--Yes, I do this
�Addition, subtraction, multiplication, and division of real numbers--Of course
�Probability and odds--Yes
�Rates, ratios, and percents--Yes
�Exponents and powers--I don't feel like this comes up a lot but it's pretty simple
�Order of operations--Yes
�Functions--Hell to the no
�The distributive property--Yes
�Linear equations--I only vaguely remember what this is
�Formulas and functions--No
�Quadratic equations and functions--No
�Polynomials and factoring--No
�Rational equations and functions---No
�Pythagorean Theorem--I may have used it very rarely, but generally no

FWIW, I handle the family budget.
