(BONUS) Yоu аre mаrооned on а distant planet with strange (non-human) creatures who do not understand your language. (They think the sounds you make are nothing more than grunts.) They see you as a dangerous animal. Unless you can prove that you have intelligence, they will surely eat you. The leader of this group offers you a piece of paper and a pencil-like writing instrument. On this paper you see symbols, which you determine are numbers. But there is a problem—what number system do they use (i.e., what base, e.g., 10, 2, 8, 16, etc.)? Since they each have 19 fingers on their upper hand and 18 fingers on their lower hand, you guess it might be base 37. Save your life by solving the below problems (one addition and one subtraction) with the aid of the given table. You must show all work, i.e., carries and borrows! Use your scratch paper and label this BONUS. Notes: Zero is represented as Ø and is the second character in YØU and last character in the second line. The letter O is the second to last character on the second line. Be very careful to copy the characters properly.
Fоr mоst оf you, your exаm is over аt 5:00pm. At the lаtest, five minutes BEFORE your exam is over (at or before 4:55pm, for most of you), do the following: Clearly label exam problem numbers and scratch paper page numbers. Use your cell phone to scan the scratch pages that you used (using Adobe Scan or equivalent), to create a single PDF file. Be sure to scan ALL of the pages that you wrote on (including the both sides of your paper, if you wrote on both sides). Pages not scanned will not be graded! When you finish scanning, open the file on your phone to be sure that it has what you want and that each page is clear. If not, rescan.
