## A |
---|

## absolute valuethe value of a number without regard to its sign | |

## Addition Property of Equalityallows us to add the same amount to both sides of an equation: For all real numbers a, b, and c, if a = b, then a + c = b + c | |

## Addition Property of Identitystates that any number plus zero equals that number: For all real numbers a, a + 0 = a | |

## Additive Inverse Propertystates that every real number added to its additive inverse (or opposite) will equal zero: For all real numbers a, a + (-a) = 0; also called Inverse Property of Addition | |

## algebrathe branch of mathematics that deals with operations on sets of numbers and relationships between them | |

## area modela graphic representation of a multiplication problem, in which the length and width of a rectangle are the factors and the area is the product | |

## Associative Property of Multiplicationstates that numbers in a multiplication sequence can be multiplied in any order, and the value of the expression will not change: For all real numbers a, b, and c, (ab)c = a(bc) | |

## axis of symmetrya line of symmetry for a graph - it divides a figure or graph into halves that are the mirror images of each other | |

## B |
---|

## basethe value that is raised to a power when a number is written in exponential notation. In the term 53, 5 is the base and 3 is the exponent. | |
