It seems you're referring to a URL or project name: (note the likely correction from "oi" to "io", as GitHub Pages typically use the .io domain).

Before using any .github.io educational site, verify its content and safety, as GitHub Pages can host both high-quality projects and outdated or unofficial copies. When in doubt, look for the author's name, license information, and a link to the source repository. Last reviewed: April 2026 mathsframe.github.oi
