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.

+= |
Addition | 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 |

|| |
