Instructions
No calculator allowed! No calculator allowed! No calculator allowed! No calculator allowed! Initial here ___ to indicate that you have actually read these instructions. If you attempt to use a calculator made by Texas Instruments or any of the other principal manufacturers to solve these problems, a special detector will activate a hidden microprocessor that will give you bad breath, scramble your cell phone’s memory, and leave you in a state of general confusion throughout the month of November.
