Math 170: Quiz 1


Instructions

This quiz is part of the first exam and is worth 20 points.

You are encouraged to work in groups of up to three students. Turn in one paper per group, not one paper per student. Include the names of all people in the group on the paper.

This quiz is due the day after the in-class exam. However, I urge you strongly to complete it before the in-class exam as it will help with the problems on the in-class exam.

You will need access to the world wide web to complete this portion of the exam.

You may include printouts from the world wide web as part of your quiz -- you do not need to rewrite all the information (although you may).

All information here can be found at the Illinois Community College Board http://www.iccb.state.il.us under the system resources they have made available.
