# Operator

1. In computer programming and at the command line, an **operator** is an object that is capable of manipulating a value or operator. For example, in "1 + 2", the "1" and "2" are the operands and the plus symbol is the operator. Below is a listing of common operators found in programming languages with explanations and examples.

Operator | Alternative | Explanation | Examples |
---|---|---|---|

= | Eq | Equals | a = b |

== | Eq | Equals | a == b |

!= | Ne | Not equal | a != b |

+ | Plus | a + b | |

+= | Addition | a += b | |

++ | Increment | a++ | |

- | Minus | a - b | |

-= | Subtraction | a -= b | |

-- | Decrement | a-- | |

/ | Divide | a / b | |

* | Times | a * b | |

> | Gt | Greater than | a > b |

< | Lt | Less than | a < b |

>= | Ge | Greater than or equal to | a >= b |

<= | Le | Less than or equal to | a <= b |

|| | or | Boolean or | a || b |

&& | and | Boolean and | a && b |

Booleans are also considered operators where AND, OR, and NOT can also be used in most programming languages.
