CALC 1 uses the following keys for register arithmetic and repetitive adding, subtracting, multiplying and dividing.

Key Label | Hint | X Formula |
---|---|---|

STO ra÷x | Divides the register arithmetic variable by x. | raValue = raValue / rgX() |

STO ra*x | Multiplies the register arithmetic variable by x. | raValue = raValue * rgX() |

STO ra-x | Subtracts x from the register arithmetic variable. | raValue = raValue - rgX() |

STO ra+x | Adds x from the register arithmetic variable. | raValue = raValue + rgX() |

RCL x÷ra | Divides x by the register arithmetic variable. | rgX() / raValue |

RCL x*ra | Multiplies x by the register arithmetic variable. | rgX() * raValue |

RCL x-ra | Subtracts the register arithmetic variable from x. | rgX() - raValue |

RCL x+ra | Adds the register arithmetic variable from x. | rgX() + raValue |

STO ra | Stores the register arithmetic variable. | raValue = rgX() |

RCL ra | Stores the register arithmetic variable. | raValue |
