### Numbers and Operations

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

Natural numbers | counting numbers (1, 2, 3,4...) |

Whole numbers | natural numbers and zero (0, 1, 2, 3...) |

Integers | whole numbers an their opposites (...1, 0, -1...) |

Negative numbers | numbers less than zero (...-3, -2, -1...) |

Opposite | numbers that have the same distance from 0 on a number line, but on the opposite side of 0. (-7 and 7 are opposites |

rational numbers | any number that can be expressed as a fraction. |

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

Multiplication | repeated addition of a number a given number of times. |

product | the result of multiplying two more numbers. |

factors | the numbers that you multiply |

division | separating one number into a given number of equal parts. |

quotient | the answer to a division problem. |

dividend | the number thats being divided. |

divisor | the number you divide by |

remainder | the amount left over. |

divisible | when a number can be divided evenly into another number with no remainder |

multiples | the products that result from multiplying the number by each of the whole numbers |

least common multiples (LCM) | the smallest multiple two or more numbers have in common. |

greatest common factor (GCF) | the largest common factor of two or more numbers |

commutative property | shows that the order of the numbers does not change the sum of an addition problem or the product of a multiplication problem. Ex: a + b = b + a a * b = b * a |

associative property | shows that the grouping of the numbers does not change the sum or product. Ex: (a + b) + c = a + (b + c) (a * b) * c = a * (b * c) |

distributive property | uses both addition and multiplication. Ex: a(b + c) = a(b) + a(c) |

identity property | shows the sum of any number and zero is that number and the product of any number and one is that number. Ex: a + 0 = 0 a * 1 = a |

inverse property | shows that the sum of a number and its opposite is zero an the product of a number and its reciprocal is one. Ex: a + (-a) = 0 a * 1/a = 1 |

reciprocal | switching the numerator and denominator of a fraction. Ex: 1/2 & 2/1 |

zero property | shows that the product of any number and zero is zero. Ex: 5 * 0 = 0 |
