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!



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!
