#### Slide 1 -Tekstslide

Learning objectives
At the end of the lesson you
- will understand the scientific notation
- can write numbers from decimal- to scientific notation
- can write numbers from scientific- to decimal notation

#### Slide 2 -Tekstslide

Scientific notation
Paragraph 1.6

#### Slide 3 -Tekstslide

First calculate:
a.
b.
c.
104
105
3.2106

#### Slide 4 -Tekstslide

What is the scientific notation?
- Easier
- Shorter

#### Slide 5 -Tekstslide

How to use it, example
6.54105=

#### Slide 6 -Tekstslide

How to use it, example
6.54105=6.54100,000

#### Slide 7 -Tekstslide

How to use it, example

So, the            makes the decimal point move 5 places to the right.
6.54105=6.54100,000
=654,000
105

#### Slide 8 -Tekstslide

How to use it, example

So, the            makes the decimal point move 5 places to the right. This also means that:
6.54105=6.54100,000
=654,000
105
654,000=6.54105

#### Slide 9 -Tekstslide

The first factor, the number before the decimal point, is ALWAYS between 1 and 10.

5.76103=

#### Slide 11 -Tekstslide

5.76103=5.7610001

#### Slide 12 -Tekstslide

Conclusion: for the negative powers we move the decimal point to the left.
5.76103=5.7610001
=0.00576

Example:
7,890,000,000 =
7.89109

#### Slide 20 -Tekstslide

Write 257,300,000 in the scientific notation

5.76103

#### Slide 22 -Tekstslide

5.76103=5.7610001

#### Slide 23 -Tekstslide

5.76103=5.7610001
=0.00576

#### Slide 24 -Tekstslide

Conclusion:                        makes the decimal point go to the LEFT
makes the decimal point go to the RIGHT
5.76103=5.7610001
=0.00576
10negative
10positive
