Numberosity Level 1 Workshop Session 1 Summary (09/09/2023)

Today, we began our first session of our Numberosity Level 1 workshop! First, we went over how the class was going to work. This class will broadly follow the Art of Problem Solving Prealgebra book, so expect to see most concepts covered there covered in this course. (You should not buy the book, it just has what we expect to cover.) We then started looking at basic operations. Today, we went over how operations work, the order of operations, exponents, negative exponents and exponents of zero. We finished off with some practice problems.
