The AP Computer Science Principles Exam has two portions: the multiple choice section and the "performance task".
For my performance task (referred to as the "Create Task" by my teacher, hence the name of the repo), I decided to write a (rather overcomplicated) calculator for matrices.
Main.java contains executable code.
Operations.java contains a purely method contaning class that returns a new matrix based on the ones inputted.
Matrix.java contains the Matrix class.
