The Properties of Algebra By Dhara Shah

The Properties ● Commutative Property of Addition/Multiplication ● Associative Property of Addition/Multiplication ● Identity Property of Addition/Multiplication ● Distributive Property ● Equality Property of Addition/Subtraction/ Multiplication/Division ● Inverse Property of Addition/Subtraction

The Commutative Property of Addition/Multiplication ● The commutative property of addition states that you can add in any order and the sum will stay the same ● The commutative property of multiplcation states that you can multiply in any order and the sum with stay the same Example:

The Associative Property of Addition/Multiplication ● The associative property states you can group any two numbers together and the answer will be the same Example: (1+2)+3=1+(2+3) (1x2)x3=1x(2x3)

The Identity Property of Addition/Multiplication ● The identity property states that the sum of any number and 0 equals the number itself ● Example: ● 4+0=4

The Distributive Property ● The distributive property is when you split the multiplication or in other words distribute ● Example: ● 5(2+3)=5(2)+5(3) ● =10+15

The Equality Property of Addition, Subtraction, Multiplication, and Division ● The equality property states that both sides of an algebraic expression must be balanced in order for the expression to be true ● Example: ● If a=b then a+c=b+c ● If a=b the a-c=b-c ● If a=b then axc=bxc

The Inverse Property of Addition/Multiplication ● The inverse property of addition states that a number plus the same negative number always equals 0 ● The inverse property of multiplication states that any number multiplied by the fraction of that number always equals 1 ● Example: ● 4+(-4)=0
