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

Algebraic expression | A mathematical phrase involving at least one variable and sometimes numbers and operation symbols. |

Associative Property | The sum or product of a set of numbers is the same no matter how the numbers are grouped. |

Coefficient | A number multiplied by a variable in an algebraic expression. |

Commutative Property | The sum or product of a group of numbers is the same regardless of the order in which the numbers are arranged. |

Cubed | A number to the third power |

Equation | A mathematical sentence that contains an equal sign |

Exponent | The number of times a number or expression (called base) is used as a factor of repeated multiplication. Also called the power. |

Inequality | A mathematical sentence that contains the symbols >, <, ≥, or ≤. |
