## How does scientific notation work?

Scientific notation is a way to make these numbers easier to work with. In scientific notation, you move the decimal place until you have a number between 1 and 10. Then you add a power of ten that tells how many places you moved the decimal. In scientific notation, 2,890,000,000 becomes 2.89 x 109.

## What is correct scientific notation?

The proper format for scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.

## What are the 2 parts of scientific notation?

• Just the digits, with the decimal point placed after the first digit, followed by.
• × 10 to a power that puts the decimal point where it should be. (i.e. it shows how many places to move the decimal point).

## What are the 3 parts of a scientific notation?
