Some numbers are too cumbersome to write down in our usual decimal notation, either because they are too large (for example 293,000,000,000,000,000,000,000) or because they are too small (for example 0.0000000000000000000000044). Writing these numbers in scientific notation allows us to express these numbers in a much more compact form.
InstructionsIn this exercise you are given a number in either the decimal or scientific format, and are required to convert it to the other. Using the options you can elect
Enter your answer using the keyboard. Press the 'x' key, and the computer will recognize that you now wish to enter the exponent of a number in scientific format. If you make a mistake, you can correct it using the backspace key. 
Arithmetic in Scientific NotationIn the next exercise, you will practice multipying and dividing numbers in scientific format.
