More on scientific notation

There are many ways to convert numbers from scientific notation to standard form. You could estimate the product and use that to verify your answer. For example 2.08 x 10^2 is close to 2 x 10^2. Since 2 x 10^2 is 200, you know that the answer to 2.08 x 10^2 is close to 200. So the answer is 208. Or you could move the decimal point according to the power of 10 that you have. If you have 3.16 x 10^3 you could move the decimal point three spaces to the right from where it is in 3.16. When you do that you end up with 3160.
