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
copy

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

Task

Perform the following calculations using basic arithmetic operations:

  1. 30 + 24;
  2. 50 - 36;
  3. 19 * 7.

After completing these tasks, press the button below the code to check your answers.
