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 |
