Continuing to mess with this realizing:
1) I have totally let my times tables languish 💀
2) you can check your math far better with this approach
3) I really need to make my 1s and 2s clearer
4) It really lets you see just how big the math you are doing is, it really starts to shine when your result tips over the millions and billions.
