## Survey of Mathematics

Welcome to MATH103, A Survey of Mathematics. I am excited to be joining you in this course, and I hope that you are as excited about taking it. If you are new to the Blackboard system, take some time to familiarize yourself with all the many resources that are available to you in here. The course shell can be a bit intimidating at first, but once you get comfortable with how it works, you will be navigating like a pro.

In week 1, you will be taking your Knowledge Assessment, which can be found under the Activities folder. While your score on this assignment does not count toward your grade, it will give you a better idea of where your strengths and weaknesses lie.

## Here is a quick description of Math103, taken from your course syllabus:

Students employ a wide range of problem solving strategies. This course introduces measurement, consumer math, quantitative reasoning, statistics, different numeration systems, and optional topics according to student needs.

## A puzzle to get you started

Let’s say that you have 9 coins, all of the same denomination, and that these coins are identical in every way, except that one of them is counterfeit. The only way you can tell which coin is the false one is because it weighs less than the others. You are given one of those old fashioned balance scales as your only measuring tool. How can you determine which is the fake coin using the fewest amount of weighing attempts on the scale?
