All of you are telling him to get to the point probably don't realize he's alluding to his past career at De Shaw (Fat stacks of 100s, interest for math) and how he began before aops (San Diego Math Circle). Also he's talking in a childish tone and inserting the story into it because he wants to keep the attention of children. This is for children not adults. I have no idea why random adults/high school students are commenting on the childish tone of this.

@SawanKokar If Superman sits on the right edge (1st position) There are zero ways you can arrange batman and wonderwoman so that superman is between them

Can it be possible for a person to to be a genius and not have good math skills? Like having dyslexia.

D: it's not slow for me and the tone is neither childlike nor distracting. Interesting opinions/criticism you've got there but don't think they're facts :D and plus the only reason it hasn't broken 5000 views is because ... well, the demographics of America...
