Example 

var total_price = ticket_price * number_of_tickets

The characters = and * are operators. ticket_price and number_of_tickets are operands of the multiplication, and total_price is the left operand of the assignment.

Multiplying has the highest precedence; otherwise the assignment would not make sense. You can view all operators and their precedence in the following table.

Description

= 1 Assign a value to a variable
+= 1 A shortcut for x = x + ...
-= 1 A shortcut for x = x - ...
*=  1 A shortcut for x = x * ...
/= 1 A shortcut for x = x / ...
::= 1 A shortcut for x = x :: ...
|| 2 Boolean operator that evaluates to true if and only if either of its operands are true
&& 3 Boolean operator that evaluates to true if and only if both of its operands are true
== 4 Boolean operator that evaluates to true if and only if both of its operands are equal
!= 4 Boolean operator that evaluates to false if and only if both of its operands are equal
> 5 Boolean operator that evaluates to true if and only if the number value of the left operand is greater than the number value of the right operand
< 5 Boolean operator that evaluates to true if and only if the number value of the left operand is less than the number value of the right operand
>= 5 Boolean operator that evaluates to true if and only if the number value of the left operand is greater than or equal to the number value of the right operand
<= 5 Boolean operator that evaluates to true if and only if the number value of the left operand is less than or equal to the number value of the right operand
+ 6 Arithmetic addition of the number values of the two operands
- 6 Arithmetic subtraction of the number values of the two operands
:: 6 Concatenation of the string values of the two operands
* 7 Arithmetic multiplication of the number values of the two operands
/ 7 Arithmetic division of the number values of the two operands
% 7 Modulo operation with the left operand as the dividend and the right operand as the divider
^ 7 Exponential operation with the left operand as the base and the right operand as the exponent
Unary Operator Precedence  
! 8 Negation operator that evaluates to true if the operand is false
--x 8 Decrement x by 1 and return (x - 1)
x-- 8 Decrement x by 1 and return original value of x
++x 8 Increment x by 1 and return (x + 1)
x++ 8 Increment x by 1 and return original value of x
@x 8 Mark variable x as a String constant. This will prevent all number operations on this expression.
