If you're doing a slightly more complex math equation using exponents, you won't find the necessary symbols on a standard keyboard. However, computers are capable of utilizing a plethora of special characters with “Alt” code commands. Typing the right sequence on a standard keyboard lets you insert the second power in virtually all PC programs.
