What is the identity property of addition
The sum of zero and a number is that number
What is the commutative property of addition
Changing the order of the addends does not change the sum
What is the associative property of addition
Changing the grouping of addends does not change the sun
What is a divisor
A number by which another number, the dividend, is divided
What is a dividend
A number divided by the divisor
What is a terminating decimal
The decimal stops or ends
What is a repeating decimal
The decimal repeat the same number or set of numbers
What is an additive inverse
Two numbers whose sum is zero
How do you add integers that have the same sign
Add and keep the same signs
How do you add integers that have different signs
Find the difference and then the sum has the sign of the integer with the greater absolute value
When multiplying integers product of two integers with the same sign is
Positive
When multiplying integers the product of two integers with different signs is
Negative
When dividing integers the quotient of two integers with the same sign is
Positive
When dividing integers the quotient of two integers with the different sign is
Negative
What is the measure of central tendency
A single central value that summarises a set of data
How do you find the mean
Sum of the data items divided by the number of data items
How do you find the median
The middle value, or the mean of two middle values, those when data are in numerical order
What is the mode
The item with the greatest frequency
What is the range
Difference between the greatest and the least values in a data set
What is an outlier
If a datà set has one item that is much higher or lower than the other data items
What are the steps to multiplying decimals
Multiply as if the factors are whole numbers.
Count the number of decimal places in both factors
Your total numbers of decimal places needs to appear in your product as well
What is the Identity Property of Multiplication
The product of one and any number is that number
What is zero property of multiplication
The product of zero and any number is zero
What is the community of property of multiplication
Changing the order of the factors does not change the product
