Introduction to R Syntax

Calculations

Let’s start with the basic syntax for mathematical calculations in R. R performs addition, subtraction, multiplication, and division with `+`

, `-`

, `*`

, and `/`

:

# Results in "500" 573 - 74 + 1 # Results in "50" 25 * 2 # Results in "2" 10 / 5

Mathematical operations in R follow the standard mathematical order of operations. Let’s write your first line of R code and calculate some basic math!

### Instructions

**1.**

Calculate the result of this equation: `25 * 4 + 9 / 3`

in the R code block in your **notebook.Rmd** R-markdown file. Before you press run, try to figure out what the answer would be based on the order of operations. Your answer should match the output!
