Properties of multiplication:

Which property of multiplication is shown?


u · 0 = 0
zero
distributive
associative
identity

   


The anwser is zero because...
There are four properties involving multiplication that will help make problems easier to solve. They are the commutative, associative, multiplicative identity and distributive properties.
Commutative property: When two numbers are multiplied together, the product is the same regardless of the order of the multiplicands. For example 4 * 2 = 2 * 4
Associative Property: When three or more numbers are multiplied, the product is the same regardless of the grouping of the factors. For example (2 * 3) * 4 = 2 * (3 * 4)
Multiplicative Identity Property: The product of any number and one is that number. For example 5 * 1 = 5.
Distributive property: The sum of two numbers times a third number is equal to the sum of each addend times the third number. For example 4 * (6 + 3) = 4*6 + 4*3



since it none of these it has to be zero :)




properties of adtition:



Which property of addition is shown?

(2 + 3) + 9 = 2 + (3 + 9)
associative
commutative
identity
  The answer is associate because....

As you can see associative is displayed with brackets and + making it easy to tell.
My next goal is to start working on my next goal and try to complete it.

Goals term 4 reflections


1. For goal one which is  always to complete  my SDL on time. Here is how and if I have been goinng throughout the year
I think I've completed this goal because I always compete goal before deadline and always do homework on time so I don't have to stay in


2.  get more involved 

I think I've completed this goal because at lunch I'm either on the basketball court or  playing with the little kids instead of just sitting around
