Hi everyone, this is Brady Harron.

I make the Numberphile podcast and the Number File videos.

For something a bit different today, you're going to interview me.

I'm not going to get to be the interviewer and hide behind the camera or the microphone.

I'm going to answer your questions.

A bunch of been sent in by Patreon supporters and Twitter followers, Facebook followers, all that

kind of stuff. I've collated them a little bit into groups. There was some duplication,

and there were too many questions to do all of them. So sorry if I don't ask your question,

or it's wrapped in with another one, but I appreciate everyone who got in touch. All sorts of great questions, from things I expected to things I didn't. I'll do my best. It's quite a weird feeling sort of sitting on my own, not having someone to interview or talk to. It does feel odd, but hopefully it works out. I'm closing my eyes and trying to imagine

you're all here with me. First, a question from Raz. Raz said, first of all, sound check. What did

you have for breakfast? Raz is obviously showing a bit of insider knowledge there. A lot of people

who do my job ask a question at the start of all interviews to sort of calibrate

the sound levels. It's something arbitrary and most people just tend to ask, what did you have

for breakfast? Because it's a question. Almost everyone can answer. They'll answer with a sentence

or two and you can use those few seconds to check the audio levels on your equipment. I've also

made a compilation video many years back now where I put together all the sound checks. I think I called it, what do mathematicians eat for breakfast? What did I have for breakfast today? Well, I'm recording this very early in the morning because there's some construction work being done near my office and I know a whole bunch of drills and jackhambers are going to start later on.

So I've gotten up very early to record this and it means I actually haven't had breakfast yet.

If you'd ask me another morning I may have answered steel cut oats, which is a new thing I'm

experimenting with at the moment and I really enjoy them. Steel cut oats. Check it out.

A few questions along these lines. No Lord said,

what is your relationship with mathematics? Did you study it? What do you like about mathematics?

Brin asked, what's the highest level of math or math you completed in school? What got you interested in math. So to answer that
