About this project

We optimize for one job: help you add and subtract polynomials with confidence on any device.

Adding and Subtracting Polynomials Calculator exists because algebra steps deserve the same clarity as larger math apps. The layout uses concrete-gray structure, sharp edges, and compact spacing so you can move from inputs to R(x) in seconds.

Everything ships as static HTML, CSS, and Alpine.js. That keeps hosting simple on Cloudflare Pages and avoids sending your coefficients to a backend.

Content lives in structured JSON so guides can be updated without hunting through templates.
