If you have any questions, please contact me by e-mail (john.uccellini@umuc.edu). At the end of your quiz you must sign the following dated statement with your name typed in lieu of a signature.

If there is no work to show, then include a sentence or two explaining your answer. Here are the basic rules of showing work: Each step should show the complete expression or equation rather than a piece of it. Each new step should follow logically from the previous step, following rules of algebra. Each new step should be beneath the previous step. The equal sign, =, should only connect equal numbers or expressions. If you have questions about showing work, please ask.
