Add more napkin math problems to https://sirupsen.com/

Hi @sirupsen - not sure if this is the right place to post this, but I've done most of your napkin math problems on your website, and would love to do more, if you could make them. Granted, I'm sure it takes a while to come up with and solve these problems. So, I noticed we could use ChatGPT to generate these problems and create a initial solution: These are not the best but you could make better ones, if you give it a topic and some more details. <img width="638" alt="Screen Shot 2023-03-21 at 10 28 28 PM" src="https://user-images.githubusercontent.com/12554095/226786286-4fbe6fa8-fd02-499f-8aee-af3cc2e1b6dd.png"> <img width="699" alt="Screen Shot 2023-03-21 at 10 30 50 PM" src="https://user-images.githubusercontent.com/12554095/226786619-29a6be7d-644d-4ccd-a7f1-d55546fb4157.png">
