Math Properties

Associative Property of Addition

When adding numbers, grouping doesn't matter. Example: (2+4)+6=(4+6)+2

Idenity Property of Multiplication

You can multiply any number by 1 and get the original number that you started with. Example: 5x1=5

Idenity Property of Addition

The property that states that when you add zero to the number the result is that number. Example: 1+0=1

Distributive Property

A number outside the parenthesis can be multiplied to each term within the parenthesis. Example: a(b+c)=ab+ac

Inverse Property of Multiplication

A numbers reciprocal. Example: 20/5=4/20x1/5=20/5=4

Inverse Property of Addition

The sum of a number and its opposite is 0. Example:-4+4=0

Closure Property

The sum or product of any two real numbers is a real number. Example: 2+4=6, or 3x4=12

Associative Property of Multiplication

When multiplying numbers, grouping doesn't matter. Example:(5x3)x7=5x(3x7)

Commutative Property of Multiplication

No matter what order the numbers are in, both sides of the equation should be the same when it's multiplied. Example: 2x3=3x2

Commutative Property of Addition

The order in which numbers are added does not change the sum. Example: a+b=b+a
