6 Arithmetic Operator

• Standard arithmetic operators are similar

• Exponentiation is different in R & Python

---

6.1 R

x <- 5; y <- 3 OR x = 5; y = 3

Operator	Explanation	Example
+	Addition	x + y
-	Subtraction	x - y
*	Multiplication	x * y
/	Division	x / y
%%	Modulus	x %% y
%/%	Integer division	x %/% y
^ (**)	Exponentiation	x ^ y; x ** y
()	Parenthesis (precedence rule)	(x + y)*3

6.2 Python

x = 5; y = 3

Operator	Explanation	Example
+	Addition	x + y
-	Subtraction	x - y
*	Multiplication	x * y
/	Division	x / y
%	Modulus	x % y
//	Integer division	x // y
**	Exponentiation	x ** y
()	Parenthesis (precedence rule)	(x + y)*3
other	C-type operation for quick assign	x += y

In python, ^ is a bitwise exclusive OR (XOR) operator
