You can use the rest of the page, which is: please draw how an algorithm works. How an algorithm works? Yes, I'll keep this on, so you can narrate it. I'm just going to draw a giant cloud, a small cloud. I'm going to write: magic formula. Okay. That's it? No. So ... It's going to be a flowchart. It's going to take- Okay. Go ahead. I haven't done one of these since I was in tenth grade, and that was, of course, only four years ago. So here's the input, and it's going to go to ... Let me see if I can still ... It's going to be a decision tree, and if it's, "If X, go that way. If Y, go that way." And just keep cascading down. I mean, because it's all computer programing, and I'm really fascinated by it. And if I was smarter when I was younger, I would've done more of that just because I think it's so interesting, but I was more interested in marijuana and girls than- Age 15. Yes. I am 15 now. No, I act like I'm 15! So my son is taking a computer programing class. I was talking to him about this. This is how we used to do it, and he's like, "Well, yeah, that's what I do in programing." I said, "Right. Programing hasn't changed. It's just a lot smarter than it used to be." How old is he? He is 17. Okay. But I mean, that's what the algorithm is taking ... He said yes, so it matches equal or similar to yes and not equal to no. So they're going to say, "Okay, best guess is it matches this." So what was the next part? Best matches this, and tries to figure it out from there. But it does it really, really fast. Okay, great. So how did you learn about algorithms? School. Yeah? Yeah, I did business data processing. They still taught typewriting in school!
