Math in Trades and Life

Math in Trades and Life is an open-access, mathematics textbook tailored for students pursuing careers in technical fields. It covers essential mathematical concepts ranging from units of measurement and ratios to geometric properties and exponential growth. It equips learners with the quantitative skills necessary for success in various trades and necessary to critically assess mathematics in their lives.

The textbook covers the following topics

1. Units (use, conversion, dimensional analysis)
2. Precision, accuracy, and error of computations
3. Ratios and Proportions
4. Linear, quadratic, exponential, and logarithmic relations
5. Solving linear equations including systems, and solving simple quadratic, exponential, and logarithmic equations
6. Reading and interpreting data in various forms
7. Geometric reasoning and calculation of perimeter, area, and volumes
8. Analysis of triangles both geometrically and with trigonometry

Below are some of the fields from which applications are drawn.

1. Auto mechanics
2. Aviation mechanics
3. Heavy equipment mechanics
4. Nursing
5. Piloting
6. Welding

Each section includes examples of mathematical principles in technical disciplines and includes exercises and projects to check and increase learning.

This textbook is freely available in web and print options, aligning with the University of Alaska Anchorage's commitment to providing open educational resources that support student success in Alaska and beyond.
