Basic Arithmetic

Unlike many other programming languages, R doesn't need a specific function to display output. So, let's begin our R journey with some simple arithmetic to get started.

In R, you can perform basic arithmetic using the following operators:

  • + for addition;

  • - for subtraction;

  • * for multiplication;

  • / for division.

For example, let's compute a few mathematical expressions:

123
12 + 21 32 - 16 10 * 11

As you can see, there's nothing complicated here.
