Maplet Exercises for Shift Ciphers

Submit your work as a Microsoft Word File. To show your work you performed to complete
each exercise using a Maplet in Microsoft Word, copy and paste your Maplet window into
your Microsoft Word page. On Microsoft Windows based machines, this can be accomplished by clicking
on the Maplet Window to make it the front window and then pressing and holding the Ctrl Alt PrtSc keys
in sequence (some machines require Function Alt PrtSc). This places the Maplet Window into the copy buffer.
On Macintosh based machines, this is accomplished by clicking on the Maplet Window to make it the front
window, pressing and holding the Command–Ctrl-Shift-4 keys in sequence, then pressing the space key, and then
clicking the Maplet Window. This places the Maplet Window into the copy buffer. You then paste the Maple
