Probabilty

I have been learning about probability. Here is evidence from the IXL games that I can now do this.

Know square numbers to 100

To figure this question first you write 65 because the number is 65 then you click the blue thing above the submit sign and then write 5 because there is 5 numbers in total.

Lets move on to the next one...

\

To figure out this what equal to the number eg 4 x 4 = 16 then the answer would be 4 ,but for this we need to figure out what = 9 (in the time-tables) which is 3 :)

Maths goal- generalise properties of multiplication and division with whole numbers

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.
