Explanation:

Arithmetic with R

In its most basic form, R can be used as a simple calculator. Consider the following arithmetic operators:

  • Addition: +
  • Subtraction: -
  • Multiplication: *
  • Division: /
  • Exponentiation: ^
  • Modulo: %%

The last two might need some explaining:

  • The ^ operator raises the number to its left to the power of the number to its right: for example 3^2 is 9.
  • The modulo returns the remainder of the division of the number to the left by the number on its right, for example 5 modulo 3 or 5 %% 3 is 2.

With this knowledge, follow the instructions below to complete the exercise.
