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.

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 |
