Chapter 3: Measurements

As we finished our Chapter 2 Test a new Chapter is introduced.

This beginning is Scientific Notation and Decimal Placing

So we learned that decimal placing can vary from one, ten, hundred to tenth, hundredth, etc.

Meaning where to put the decimal and where to cut off the numbers. Like in 456.789

One: 457   Ten: 460 Hundred: 500  Tenth: 456.8 Hundredth: 456.79   ……

Scientific Notation

Is where up in the image the standard notation would be for ex: 24,000,000 $ but in Scientific Notation it becomes 2.4 x 10 to the power of 13

In Scientific Notation the number always remains atleast one but no less than ten, hence the 24 – 2.4 then takes all the 10’s and repeats it.
