JavaScript arithmetic operators are used to perform arithmetic on numbers (literals or variables).
Arithmetic Operators
A typical arithmetic operation operates on two numbers. The two numbers can be literals, variables, or expressions.
| Operator | Description |
|---|---|
+ | Addition |
- | Subtraction |
* | Multiplication |
** | Exponentiation (ES2016) |
/ | Division |
% | Modulus (Division Remainder) |
++ | Increment |
-- | Decrement |
Addition and Subtraction
The addition operator (+) adds numbers together. The subtraction operator (-) subtracts numbers.
Multiplication and Division
The multiplication operator (*) multiplies numbers. The division operator (/) divides numbers.
Operator Precedence
Operator precedence describes the order in which operations are performed in an arithmetic expression. Multiplication (*) and division (/) have higher precedence than addition (+) and subtraction (-).
As in traditional school mathematics, the precedence can be changed by using parentheses.
