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.
PLEASE COMMENT!!!
