# Properties #### Storyboard Text

• Hi my name is Josh, today I'm going to teach you﻿ about the five properties of addition and multiplication
• ﻿This property means the order doesn't matter at all it will always give you the same answer no matter what.This only applies in addition and multiplication.
• First I will show the meaning and some examples of commutative property.
• Here is an example: 7+4 = 4+7 = 11 8*4 = 4*8 = 32
• This means that it doesn't matter the way you order the parentheses because it will not affect the result.And again this only applies in addition and multiplication
• Now let me tell you about the Associative Property
• Here is an example: 6+(9+4) = 9+(6+4) = 19 2*(5*3) = 5*(2*3) = 30
• As it says it in the name this only applies in addition.This property means when you add 0 to another number the answer is always the numer.
• We are almost done just 3 more properties.Here is the next one: Additive Identity
• ﻿Here is an example: 7+0 = 7 0+6 = 6
• Now the multiplicative identity only works on multiplication obviously.This one is easy any number times 1 is always the number
• Only 2 more.The next one is the Multiplicative Identity
• Here is an example: 8*1 = 8 1*4 = 4
• Here we have the easiest of all the properties.This one means that every number that you multiply by zero will be zero.
• And finally the last one.Now we have the multiplicative property of zero
• Here is an example: 3*0 = 0 0*7 = 0
