The quiz is divided into multiple choice problems and word problems. The multiple choice problems consist of questions which have pictures corresponding to the different choices. These problems test your ability to visualize solutions when different options are presented. The word problems involve a combination of reasoning and/or hand calculation. These problems test your ability to work out solutions without the benefit of a visual aid. This is often the case when having to solve real world problems.

The answers for the problems are given at the end of the page.
