Arithmetic in R (1)
Let's play around with your new calculator. First, check out these arithmetic operators, most of them should look familiar:
- Addition:
+ - Subtraction:
- - Multiplication:
* - Division:
/ - Exponentiation:
^or** - Modulo:
%%
You might be unfamiliar with the last two. 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 the right, for example 5 modulo 3 or 5 %% 3 is 2.
Lastly, there is another useful way to execute your code besides typing in the R Console or pressing Submit Answer. Clicking on a line of code in the script, and then pressing Command + Enter will execute just that line in the R Console. Try it out with the 2 + 2 line already in the script!
