The main topics introduced in this chapter, permutations and combinations, form part of the overall branch of mathematics known as combinatoricsCombinatorics. Combinatorics is primarily concerned with counting. We will learn here how to count the number of ways that items can be arranged, and how many ways we can select items from a larger groups of items. We will later go on to explore how this topic provides a convenient way of expanding binomial algebraic expressions.
