### Bruce's Scribepost, Nov.19

Hey guys,

Well today we went over some of the homeworrk we were assigned to do.
For example...
Factors of...
1-1
2-1,2
3-1,3
4-1,2,4
5-1,5

We also went over some definitions, such as...
Square Numbers-the product of a whole number multiplied by it self
Example...9=3x3
Factors-a whole number which divides evenly into a whole number leaving no remainder.
Example...16=1,2,4,8,16
Prime Numbers-a whole number greater than 1, that has only 2 factors. The 2 factors are 1 and itself.(1 is not a prime number)
Example...
2,3,5,7,11,13
Prime Factors-factors that are prime numbers.
Example...
10=1,2,5,10(the prime factors are 2 and 5)

After homework check we went into Prime Factorization.
Here are a few examples.
18=2x3x3
24=2x2x2x3
36=2x3x2x3
144=3x4x3x4
144=2x2x2x3x2x3
I couldn't draw a factor tree so just look at Ronny's or someone who has a factor tree if you want to understand prime factorization easier.
Than the lady(can't remember her name) told us that the way to find out which one is a perfect square is that it is to have even pairs of the same numbers.
Example...
36=2x3x2x3
2 and 2 are 1 pair
3 and 3 are another pair

If you don't understand what I'm doing ask Mr Harbeck or the other teacher.

Homework is do pages 24 and 25 in your math book.

1. Hey Bruce, you made a good scribepost! I liked how you told us everything and what was important, but you should have tried a little bit harder to post pictures. Overall, you did a very good job! Btw the ''lady'' is Ms. Usiskin

2. good job explaining everything it...but it would be better if you showed us how you got the answers...

3. wow, goood job , you had practically everything we learned in class today , good job , better play good during citys !!

4. Nice Job Bruce! I liked how you gave examples and definitions! The only thing I wasn't happy about is that you didn't show how you got the answer. Anyways Great Job Bruce!

5. Good Job Bruce great knowledge of the definitions

6. good job ! I liked how you made the important things a different colour and how you told us what the homework was !
