## Overview

In a world where information and misinformation spread rapidly, it's important to learn now to think critically and become comfortable with numerical information. The applications, problem-solving emphasis, and clear writing of Mathematics All Around make it an interesting and relevant program for students of all levels and backgrounds. With new co-author Margaret Moore, the 7th Edition explores various apps, spreadsheets, and other technologies, incorporates GeoGebra and Excel Spreadsheets in some examples, and more. It is also ideal for students who need to satisfy a 1- or 2-course math requirement to transfer or graduate.
