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.
