# Order of Operations

TermDefinition
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
