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.

Instruction

• Type 2^5 in the editor to calculate 2 to the power 5.
• Type 28 %% 6 to calculate 28 modulo 6.
• Click 'Submit Answer' and have a look at the R output in the console.
• Note how the # symbol is used to add comments on the R code.
