# Frontend Math Foundations

> Explain and apply foundational math for front-end development, including arithmetic, algebra, ratios, exponents, roots, linear equations, inequalities, geometry, trigonometry, coordinates, and choosing CSS versus JavaScript math. Use when a web design calculation needs first-principles explanation before applying CSS, JavaScript, Grid, Flexbox, responsive, or color-specific skills.

# Frontend Math Foundations

Use this skill as the foundation layer for front-end math. It helps translate a visual or interaction problem into arithmetic, algebra, ratios, geometry, trigonometry, coordinates, or a CSS-vs-JavaScript ownership decision.

## Quick Start

1. Read `guidelines.md` to select the smallest relevant file set.
2. Load `references/math-foundations/rules.md` for implementation decisions.
3. Load `references/math-foundations/examples.md` when editing code.
4. Use `workflows/choose-math-approach.md` for multi-step derivation or debugging.

## Contents

| Resource | Purpose |
|----------|---------|
| `guidelines.md` | Routes tasks to the right reference files |
| `references/source-map.md` | Book source and chapter/section traceability |
| `references/math-foundations/knowledge.md` | Core concepts and terminology |
| `references/math-foundations/rules.md` | Practical rules, guidelines, and exceptions |
| `references/math-foundations/examples.md` | Bad/good examples and refactoring approach |
| `references/math-foundations/patterns.md` | Reusable formula and implementation patterns |
| `references/math-foundations/checklist.md` | Review checklist and red flags |
| `workflows/choose-math-approach.md` | Step-by-step workflow |
