This page allows you to practice predicting exponents for basic operations involving
numbers in scientific notation. When you press "New Problem" a window will appear with either a
multiplication or division problem. In the cell, enter the value of the exponent that results if the
operation is carried out and the result expressed in proper scientific notation. Then, press
"Check Answer." Results appear on the main page. When the small window appears for the first time, you may have to drag it to an empty space. From then on, it will remain out of the way. Do not use a calculator on this page or you will defeat its purpose.
