How to build a math-tutoring agent: 5-step teaching chain beats generic LLMs

The author shares how a middle schooler uses AI to study high-school math ahead of schedule, but generic models like Douban hallucinate on explanations. He outlines a teaching-oriented chain for building a tutoring skill: 1) extract conditions and the question; 2) plan the explanation order; 3) simulate blackboard-style derivation with plotted graphs; 4) let kids ask "why set it up this way" and decompose step by step; 5) follow up with variant problems to verify transfer. He then tried the vertical agent "Oula Jiangti", which showed far fewer hallucinations and better step-by-step teaching. Vertical agents embed pedagogy expertise in context engineering plus GUI optimizations generic models lack.
