724,573x746,934: I am a human calculator

This video gives an unorthodox overview on the various mental math problems I've successfully done since October of 2021, which was when I got into mental math. It briefly covers parts of a 14 page document I made explaining some of the processes I do in order to calculate a problem like: 724,573x746,934 in my head, that problem I did back in December of 2021 and did so within 15 minutes.

FYI: Many planets were destroyed in the making of this video.
