Rules for writing in Scientific Notation Step 1: Position the decimal point to get a number between 1 and 10. Step 2 Count the number of places the decimal point was moved to get the number between 1 and 10. Where did it start originally? Step 3 Write the number as a product between 1 and 10 to a power of 10 using the number of spaces the decimal moved as your exponent. If there is no decimal where does it belong?
