dnd 5e – roleplaying a high intelligence chronomancer

I am playing a 10th level chronmancer wizard in a world where chronomancy is super rare and unknown, another pc is playing an Eldritch Knight/wizard multiclass and wants too learn more. How can I properly roleplay a high int character teaching something so obviously weird? I have gotten as far as “so first you divide by zero” as an explanation for time travel, but making it work in actual roleplaying outside of magibabble isn’t working well
