## Overview

This repository is a collection of K–12 math animations intended as examples for a RAG knowledge base. Contributors add Manim scenes; the documented workflow is to render-check them and submit them. Content spans arithmetic, fractions, algebra, calculus, geometry, and measurement. A Python reviewer performs static checks and can optionally test rendering. The README says examples enter the knowledge base, but no ingestion implementation or separate statistics examples appear in the supplied tree, so those are not modeled as implemented subsystems.

Main entry points: [`review_submissions.py`](https://github.com/childe0905/manim-examples-contribution/blob/main/review_submissions.py) (Submission reviewer), [`arithmetic`](https://github.com/childe0905/manim-examples-contribution/tree/main/arithmetic) (Arithmetic scenes), [`fractions`](https://github.com/childe0905/manim-examples-contribution/tree/main/fractions) (Fraction models), [`algebra`](https://github.com/childe0905/manim-examples-contribution/tree/main/algebra) (Algebra scenes)
