In this lesson, you will learn what scientific notation is and why it is used. We use scientific notation when we need to write very large or very small numbers down. By using a power of 10, we can move the decimal point and write any number we wish in a very compact way. So, if we need to express the distance across the galaxy or the size of an atom, we can express the number using scientific notation.
