Can anyone give advice for my cousin?

I am asking you guys since I'm not really good enough at maths to help but he told me something about being stuck on dot product and said it was linear algebra so I thought posting here would be good

Is chatgpt a good teacher or is my cousin gifted?

A cousin of mine, 11 years old was doing his first year 7 homework about like some maths about me homework - nothing crazy. But somehow in like an hour of research chat taught him factorial, double factorial, functions, log and how to calculate slopes is he just smart or is chatgpt a good teacher

EDIT: He only did it for roughly 1 hour, so he only had a basic understanding no crazy stuff
