Hi Olivia,

Thanks for your suggestions! The developers currently have a long list of things to do, so I don't know if/when this content might be added. But we'll keep your ideas in mind!

Let me know if you have any further questions!

This would be a good addition to all of the pages, really. I was using the text box (the answer submission form) on my iPhone whilst trying to balance the numbers in my head as I did things like long division; it started to get a little ridiculous (and very time-consuming) – and it led to mistakes – so I now use a notepad and my MacBook. It would help, especially on the mobile platform, to have some space to work things out without having to leave the application to find some paper.
