➢The assignment operator (=) assigns a value to a variable.

➢The additionoperator (+) adds numbers:.

➢The multiplication operator (*) multiplies numbers.

➢Arithmetic operators are used to perform arithmetic on numbers:

Operator	Description
+	Addition
-	Subraction
*	Mutiplication
**	Exponentiation (ES2016)
/	Division
%	Modulus (Division Remainder)
++	Increment
--	Decrement

➢A typical arithmetic operation operates on two numbers.
➢The two numbers can be literals:

Value	Operator	Description	Example
21	( )	Expression grouping	(3 + 4)
20	.	Member	person.name
20	[]	Member	person["name"]
20	()	Function call	myFunction()
20	new	Create	new Date()
18	++	Postfix Increment	i++
18	--	Postfix Decrement	i--
17	++	Prefix Increment	++i
17	--	Prefix Decrement	--i
17	!	Logical not	!(x==y)
