Integer division is a common mathematical operation that we often use in daily life, sometimes without even realizing it.

Take, for instance, the scenario where you have 16 candies and want to divide them equally among three friends. Each friend would get five candies, with one candy left over, since 16 equals 5 times 3 plus 1. We say that the result of the **integer division** of `16` by `3` is `5`, and the **remainder** of this division is `1`.

In R, these operations are performed using:
- `%/%` for integer division.
- `%%` for the remainder of a division.

To calculate the given example in R, you would use:

# Number of candies for each friend
16 %/% 3
# Number of candies remaining
16 %% 3

In the initial section, you’ll dive into the foundational elements of R, such as generating output and performing elementary operations. This section will conclude with an exploration of the theory behind variables.

You’ll become familiar with the vector class in R, which also handles individual values. Here, you’ll delve into the primary data types for singular values and learn how to manage multiple values of the same type simultaneously.

Factors, also known as categorical variables, are prevalent in the real world. Examples include blood types, currencies, nationalities, and brands. Unlike numerical variables, factors have a limited set of possible values.
