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

3 ways to write a division problem – | dividend ÷divisor = quotient divisor)dividend quotient on top…… dividend/divisor = quotient |

absolute value – | the distance of a number from zero on a number line |

additive inverse – | the sum when you add opposites will always be 0 4 + -4 = 0 |

area – | the number of square units needed to cover a given surface |

average – | mean, add and divide by number of members |

denominator – | the number of pieces that will make a whole. |

difference – | the result when one number is subtracted from another. |

divide – | to split into equal groups |

dividend – | the number being split up x ÷ n = p x is the dividend |

divisor – | the number doing the splitting/cutting x ÷ n = p n is the divisor |

estimate – | a close answer by rounding or using compatible numbers |

evaluate – | to find the value (answer) of a numerical or algebraic expression. |

expression – | a mathematical phrase that contains operations, numbers, and/or variables |

factor – | any number that is multiplied by another number to get a product. |

fraction – | a division problem where the numerator is divided by the denominator |

improper fraction – | fractions that have a greater numerator than denominator simplify by dividing |

integer – | any whole number or their opposite—no parts no pieces |

mixed number – | a non-zero whole number and a fraction (horse shoe to simplify) |

negative number – | number less than zero. includes parts and pieces |

numerator – | the top number in a fraction, tells how many pieces are being used in question. |

opposites – | two numbers that are equal distance from zero on a number line |

order of operations – | rule for evaluating expressions (PEMDAS) |

product – | the result when two or more numbers are multiplied |

quotient – | the result when one number is divided by another |

rational number – | any number that can be expressed as a fraction or quotient of two integers. |

reciprocal – | two numbers whose product is one ¾ x ? is 1…….4/3 is the reciprocal |

simplify – | to write in simplest form |

sum – | result when one number or numbers is added to another |

variable – | a symbol used to represent a quantity that can change |

venn diagram – | a drawing that shows how members are related |

whole number – | 0, 1, 2, 3… no parts no pieces no negatives |
