Term | Definition |
---|---|

associative property | the property that allows the grouping of the numbers to change without changing the result |

closure | the property by which an answer obtained by performing an operation on any two members of a set is also in the set |

common difference | the number, d, that is the result of subtracting a term in an arithmetic sequence from the preceding term |

common ratio | the number, r, that is the result of dividing a term in a geometric sequence by the preceding term |

commutative property | the property that allows the order of the numbers to change without changing the result |

distributive property | the property by which multiplication can be done before the addition or subtraction that is contained in parentheses |

mantissa | The value in scientific notation that is ≥1 and < 10 |

characteristic | the power of ten in scientific notation |

geometric sequence | sequence in which each term after the first is obtained by multiplying the preceding term by a nonzero constant |

real numbers | all of the rational and irrational numbers |

arithmetic sequence | sequence in which each term after the first differs from the first by a constant amount |

zero exponent rule | any value raised to the zero power equals 1 |

scientific notation | product of a number ≥1 and < 10 with a power of ten |

additive identity | Adding 0 to a number does not change its value; a + 0 = a |

multiplicative identity | Multiplying a number by 1 does not change its value; a (1) = a |

additive inverse | The sum of the two numbers equals 0 |

multiplicative inverse | The product of the two numbers equals 1. |
