Represent a value with a variable.
AAP-1.A.1 A variable is an abstraction inside a program that can hold a value. Each variable has associated data storage that represents one value at a time, but that value can be a list or other collection that in turn contains multiple values.
AAP-1.A.2 Using meaningful variable names helps with the readability of program code and understanding of what values are represented by the variables.
AAP-1.A.3 Some programming languages provide types to represent data, which are referenced using variables. These types include numbers, Booleans, lists, and strings.
AAP-1.A.4 Some values are better suited to representation using one type of datum rather than another.
