Thinking About Equations: A Practical Guide For... -

Exercises and examples are grouped by the mathematical strategy they illustrate rather than by scientific subfield, which helps in recognizing patterns across different disciplines. Target Audience

The book aims to help students move beyond just solving for a variable and instead learn to "interrogate" an equation. It provides a "toolbox" of techniques—reminiscent of Richard Feynman's famous "different box of tools"—to analyze, simplify, and verify mathematical expressions in a physical context.
