Arithmetic Operators
JavaScript Arithmetic Operators
Arithmetic operators are used to perform arithmetic between variables and/or values.
Given that y = 5, the table below explains the arithmetic operators:
| Oper | Name | Example | Results | Try it |
|---|---|---|---|---|
| + | Addition | x = y + 2 | y=5, x=7 | Try it » |
| ++ | Increment | x = y++ | y=6, x=5 | Try it » |
| ++ | Increment | x = ++y | y=6, x=6 | Try it » |
| - | Subtraction | x = y - 2 | y=5, x=3 | Try it » |
| -- | Decrement | x = y-- | y=4, x=5 | Try it » |
| -- | Decrement | x = --y | y=4, x=4 | Try it » |
| * | Multiplication | x=y*2 | y=5, x=10 | Try it » |
| ** | Exponentiation | x = y ** 2 | y=5, x=25 | Try it » |
| / | Division | x = y / 2 | y=5, x=2.5 | Try it » |
| % | Remainder | x = y % 2 | y=5, x=1 | Try it » |
