### expressions and equations

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

Identify property of addition | *it has a zero in it *regular problem *simple * 66 + 0 = 66 |

Commutative property of addition | * it is the same problem on both sides *flipped the numbers *we get the same answer on both sides * 16 + 7 = 7 + 16 |

Commutative property of multiplication | * the same equation on both sides *numbers are switched *both sides of the equation get the same answer * 5 X 6 = 6 X 5 |

Associative property of multiplication | * parenthesis *same equation on both dies * flip flop the parenthesis * 7 X (2 X 3) = ( 7 X 2) X 3 |

Distributive property | * parenthesis *same equation on both sides *sharing one or more numbers * 3 X (1 + 2) = (3 X 1) + (3 X 2) |

Identity property of multiplication | * same answer on both sides * using the number one *simple * 6894 X 1= 6894 |

Associative property of addition | * parenthesis * same equation on both dies *switched the parenthesis around the numbers * (2 + 4) + 6= 2 + (4 + 6) |

equation | a math problem that includes an equal sign, both sides of the equation are equal |

Expression | numbers, symbols, and operators grouped together that show the value of something (no equal sign) |

coefficient | the number before a variable which means we multiply 4P- 4 is the coefficient |

variable | any letter that stands for a number |

operator | any of the following: addition, subtraction, multiplication, division |

order of operations | PEMDAD p-parenthesis e-exponent m- multiply d- divide a- add s- subtract |
