Mathematics at the senior high level is more than a general exposure in different areas, as compared at the middle school level. During 9th-12th grade, students take courses that are specifically for a subject in math.  In the state of Pennsylvania, students are required to take and pass 4 credits of math in order to graduate. These can include, but are not limited to, Algebra, Geometry, Statistics, Trigonometry, and Calculus. Although there are many different courses students could take, these are the ones that I am choosing to focus on, since they are the most common.
