Today I learned how to do Scientific Notation . Its pretty easy once you get the hang of it.
The rules of Scientific Notation are:
1) The first number in Scientific Notation has to be at least 1 but less then 10.
2) Multiply by a power of 10 the exponent is the number of places you move the decimal.

Example:
you would imagine there is an imaginary decimal be hind the number like this 245.
then you would move the decimal over so it is not more then 10 or less then 1 like this 2.45
then  you would out it as a power of 10 like this 2.45 x 10
and when you put it as a power of 10 you have to have an exponent above the 10 so it would be a 2.
