I wouldn't be concerned....that's all pretty standard.
I was in my late 30's when I returned to school to work on a general transfer associate's and tested in to Basic Math. I was a bit frustrated as that meant FOUR semesters of math to get through College Algebra, but math had never been my strong suit in high school.
A neighbor's sister is a high-school math teacher and she told me to start where I tested and build a strong math foundation to get me through college algebra. I finished College Algebra with a strong "B" (missed the "A" as I took a trip with a college club during the semester and missed some vital instruction!).
I'm now in my second semester of NS (at 50) and have very little problems with the math. To me, once I understand the dosing concept, it's all pretty basic compared to some of that stuff I studied in College Algebra!!
I've never had anyone question my math -- the main thing they're looking for is that you have successfully met the minimum
math requirement with the grade that is required. I definitely wouldn't let this worry you, but you can always check with the schools you're interested in!!
