On the computer, we will be using the "^" symbol to denote that the number following the ^ is an exponent. Thus 2^3 stands for 2x2x2, cm^3 stands for cubic cm. This can be used to write a number in scientific notation, e.g., 2300 can be written as 2.3x10^3. We will also use the convention of representing x 10^ with E. Thus 6.2E4 represents 6.2 x 10^4.
