Arithmetic in R (2)
The order in which you perform your mathematical operations is critical to get the correct answer. The correct sequence of "order of operation" is:
Parenthesis, Exponentiation, Multiplication and Division, Addition and Subtraction
Or PEMDAS for short!

Which of these expressions would evaluate to 6?
