What is Distributive Property?

200

The property of addition used in the following question:

7y + 12 - 10 = (-10) + 12 + 7y

What is the Commutative Property of Addition?

300

This property of addition helps in understanding how we isolate the variable in equations that use the addition/subtraction properties of equality:

Example: x - 4 = 12

                 +4    +4

                    x = 16

 

What is the Inverse Property of Addition?

400

The property of multiplication used to solve multiplication/division property of equality problems:

Note: "/" is used for division (substitute for a fraction bar), and ' * ' is used for multiplication.

  x/5 = 20 

   *5    *5

     x = 100

What is the Inverse Property of Multiplication?

500

The property of addition used whenever we have to combine like terms.

Example:

Step 1:      6x - 29 + 11x - 11 

Step 2 :  6x + 11x + (-29) + (-11)

Step 3:           17x + (-40)
