less than | used to compare two numbers when the first number is smaller than the second number |

negative numbers | numbers less than zero |

opposites | two numbers that have the same absolute value but different signs |

positive numbers | numbers greater than zero |

rational numbers | any number that can be written as a fraction |

divisor | the number by which another number is divided |

dividend | the number that is being split; the total amount being divided |

quotient | the result of a division problem |

origin | the intersection of the x- and y-axes in a coordinate plane, described by the ordered pair (0, 0) |

coordinate plane | a system formed by the intersection of a horizontal number line, called the x-axis, and a vertical number line, called the y-axis |

quadrants | the four regions in a coordinate plane separated by the x-axis and y-axis |

ordered pair/coordinates | a pair of numbers that gives the location of a point on a coordinate grid as its value on the x and y axis (x, y) |

x-axis | the horizontal number line in a coordinate plane |

y-axis | the vertical number line in a coordinate plane |

x-coordinate | the x-value of an ordered pair, represents the horizontal placement of the point in the coordinate plane |

y-coordinate | the y-value of an ordered pair, represents the vertical placement of the point in the coordinate plane |
