Exercise

# 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 to complete the exercise.

Instructions

**100 XP**

- Type
`2^5`

in the editor to calculate 2 to the power 5. - Type
`28 %% 6`

to calculate 28 modulo 6. - Submit the 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.
