## What you’ll find in this zyBook:

### More action with less text

- Teaches math people use in everyday life, using examples like personal finance, health, home maintenance, and cooking, relevant to everyone (not just engineers and scientists)
- Used an exceptionally straightforward friendly style that alleviates math anxiety
- Includes over 150 animations and 225 question sets
- Widely praised by students as helping them realize that some math can be useful to them and that they can do that math
- Adopters have access to a test bank with questions for every chapter

## The zyBooks Approach

### Less text doesn’t mean less learning.

People use numbers and perform calculations in everyday life, often without realizing. But math education seems to assume that students will become engineers or mathematicians (most won’t), or that students enjoy doing math for math’s sake (most don’t). Instead, this material focuses on teaching the math concepts that people use in everyday life and showing application of those concepts to improve one’s life — making better decisions, saving more money, estimating more accurately, understanding media reports, and more.
