What you have to do is make sure your scientific notation is between 1 and 9.9999..... you know. then, you multiply that number by ten to a certain power-a negative or positive power; negative moving the decimal to the left and positive to the right-depending on the number you are using. For example, 6.37 x 10(to the 7 power).
