Telisa's Scribepost, Notation and Prime Factorization

Last class we needed to learn about Notation and Prime Factorization...

Before we could learn that though we needed to review the information we needed to know in order to be able to understand both better.

What are Square Numbers ?

The prouduct of a whole multiplied by itself.

What are Factors ?

A whole number which divided evenly into a whole umber leaving no remainder.

What are Prime Numbers ?

Whole numbers greater than one that can only be divided by one and itself, one isn't a prime number.

What are Prime Factors ?

Factors that are prime numbers.

For Notation we needed to learn what a Square Number was and area ( length multiplied by width )

This is what we got ...

1 = 1 * 1 = 1²

4 = 2 * 2 = 2²

9 = 3 * 3 = 3²

16 = 4 * 4 = 4²

25 = 5 * 5 = 5²

36 = 6 * 6 = 6²

49 = 7 * 7 = 7²

64 = 8 * 8 = 8²

81 = 9 * 9 = 9²

100 = 10 * 10 = 10²

121 = 11 * 11 = 11²

144 = 12 * 12 = 12²

Prime Factorization

To learn this we needed to know what a Prime Factor was, as well as a prime number and factor.

We use this to help narrow down numbes to their Prime Factors and determine if they are Square numbers or not .

examples...

18

/ \

2 9

/\

3 3

18 = 2 * 3 *3

24

/ \

4 6

/\ /\

2 2 2 3

24 = 2 * 2 *2 *3

36

/ \

6 6

/ \ / \

3 2 3 2

36 = 3 * 2 *3 *2

144

/ \

2 72

/\

9 8

/\ /\

3 3 4 2

/\

2 2

144 = 2*3 *3 *2 *2

To get the ² sign hold down alt then 253 on your keypad.
