Commutative Property of Multiplication
Can multiply in any order ie: 5x4=20 vs 4x5=20
Associative Property of Multiplication
Multiplication in different groups ie: (3x4)x2=24 vs 3x(4x2)=24
Distributive Property of Multiplication
Facts that can be broken into sum of 2 different facts ie: 7x4=(5x4)+(2x4)
Identity Property of Multiplication
Multiplying any factor times 1 (8x1=8)
Zero Property of Multiplication
Multiplying any factor times 0 (8x0=0)
The difference in the largest number and the smallest number in a set
The middle number in a set. If the set has an even number of numbers, then the it is the average of the two middle numbers in the set.
Average the middle 2 numbers of the set
If the set has an even number of numbers, then how do you find the Median?
The number that occurs most frequently in a set of numbers.
The average of a set of numbers. (All of the numbers added together and divided by the total amount of numbers in the set.)

Additive Identity Property
When you add 0 to any number, the number keeps it's identity. (8+0=8, 0+8=8)
Additive Inverse Property
Adding a number to another number to equal 0 (-5+5=0)
