R Introduction: Part I

bookBasic 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.
