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

integers | Whole numbers and their opposites. |

negative numbers | a number less than 0. |

opposites | two numbers whose sum is 0. |

positive numbers | a number greater than 0. |

rational numbers | a number that can be represented as the quotient of two integers with the divisor not being 0. |

algorithm | Steps you follow to solve a problem. |

Commutative Property | Order doesn't matter in addition or multiplication. |

absolute value | the distance a number is away from 0 on a number line. |

additive identity | For rational numbers, it's zero. Add zero to any rational number and the sum is the original number. ex:1/2 + 0 = 1/2 |

additive inverse | Two rational numbers that when added together equal zero. ex: (+3/4) + (-3/4) = 0 |

multiplicative identity | For rational numbers it's 1. This means that you can multiply any rational number by 1 and you will end up with your original number. ex: -3/5 x 1= -3/5 |

multiplicative inverses | Two numbers that can be multiplied together to equal 1. ex: 4 x 1/4 = 1 |

Order of Operations | the order that all operations must be done in. "Please excuse my dear aunt Sally" or P.E.M.D.A.S: parenthases & exponents, multiplication & division, then addition & subtraction |

Distributive Property | 2 (3+4) = (2x3) +(2x4) |

expanded form | The form of an expression made up of sums or differences of terms rather than products or factors. ex: 15+5 |

factored form | The form of an expression made up of products rather than sums for differences. ex: 5( 3+1) |

number sentence | A mathematical statement that gives the relationship between two expressions, made up of numbers and operation signs. |
