Move the decimal so there is only one number to the left
Count the number of places as you move
If you move the decimal LEFT the exponent is POSITIVE
If you move the decimal to the RIGHT the exponent is NEGATIVE

4. Check Your Work!
If the original number is greater than 1 the exponent is POSITIVE
If the original number is less than 1 the exponent is NEGATIVE

5. Examples
3,600,000 = ?
