This chapter is a tour through divisibility rules and lessons in the basics of exponents and calculations involving exponents in the order of operations. You will then revisit and master factoring, including finding the GCF before simplifying fractions and converting between improper fractions and mixed numbers. A most awesome quick journey through rational numbers is next. The chapter closes out with a detailed look at the rules of exponents and scientific notation. You will come away with an understanding of why the rules make sense and how they built off one another!!
