Most RN programs only require algebra one and two and geometry, but will I need additional math courses to get my bachelors in nursing or to become a nurse practitioner?

I don't see why you need any special maths. From what I can see in Australia you just need maths in your final year of high school. This basically means you can do probability, geometry, and algebra.

There are nursing calculations books available, if you can easily do these then you won't have any trouble (they are not very hard).
