# Order of Operations

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

identity property of multiplication | if you multiply a number by one, the product is the same as that number |

braces { } | can be used to indicate that the objects written between them belong to a set |

equal | having the same amount, size, or value |

equal groups | groups that contain the same number of objects |

commutative property of addition | changing the order of the addends does not change the sum |

multiplicative comparison | compare by asking or telling how many times more one amount is as another |

evaluate | to find the value of a mathematical expression |

symbol | something that stands for, or represents, something else |

related facts | related addition and subtraction facts or related multiplication and division facts |

sequence | a set of numbers arranged in a special order or pattern |

is not equal to | is not the same as |

unknown | the missing part of number in a problem |

order of operations | a set of rules that tells the order in which to compute |

associative property of addition | changing the grouping of three or more addends does not change the sum |

sum | the answer to an addition problem |

identity property of addition | if you add zero to a number, the sum is the same as that number |

row | a straight line of objects or symbols that is lined up side to side |

difference | the amount that remains after one quantity is subtracted from another |

function table | a table that lists pairs of numbers that follow a rule |

multiplicative identity property of 1 | if you multiply a number by one, the product is the same as that number |

parenthesis | used in math as grouping symbols for operations |

estimate | a number close to an exact number, it tells about how much or about how many |

corresponding terms | terms that are in the same sequence of numbers |

associative property of multiplication | changing the grouping of three or more factors does not change the product |

column | a straight line of objects of symbols that is lined up and down |

subtract | an operation that gives the difference between two numbers |

operation | a mathematical process, the most common operations are multiply, divide, add, and subtract |

model | a visual picture or drawing of a math problem or concept |

additive comparison | problems that ask how much more (or less) one amount is than another |

variable | a letter or symbol that represents a number |

reasonableness | an answer based on good number sense |

prime number | a whole number greater than zero that has exactly two different factors, 1 and itself |

factor pairs | a set of two numbers when multiplied, will result in a given product |

composite number | a number greater than zero that has more than two different factors (any number that is not a prime number) |

commutative property of multiplication | changing the order of the factors does not change the product |

term | a number, variable, product, or quotient in an expression; NOT a sum or difference |

distributive property | when one of the factors of a product is a sum, multiplying each addend before the product |

expression | a mathematical phrase without an equal sign |

factor | the whole numbers that are multiplied together to get a product |

multiple | a product of a given whole number and any other whole number |

equation | a math sequence with an equal sign; the amount on one side of the equal sign has the same value as the other side |

brackets [ ] | a type of grouping symbol used in pairs that tells what operation to complete first |
