## Operators

The most common type of JavaScript expression is the numeric expression that combines numeric operands and arithmetic operators to produce a numeric result. JavaScript's basic **arithmetic operators** are more or less the same as those found on the numeric keypad of most modern computer keyboards, plus a couple of extra operators for more advanced work.

Operator | Name | Example | Result |
---|---|---|---|

+ | Addition | 10 + 4 | 14 |

++ | Increment | 10++ | 11 |

- | Subtraction | 10 - 4 | 6 |

- | Negation | -10 | -10 |

-- | Decrement | 10-- | 9 |

* | Multiplication | 10 * 4 | 40 |

/ | Division | 10 / 4 | 2.5 |

% | Modulus | 10 % 4 | 2 |

Example: Using the + Operator

<script language="JavaScript" type="text/javascript"> <!-- var number1 = eval(prompt("Enter the first number:", 0)) var number2 = eval(prompt("Enter the second number:", 0)) var sum_result = number1 + number2 alert(sum_result) //--> </script>
