Done!
171/111 I hope you didn't want me to simlify.
...wait? this wasn't about Algebra? You were actually talking about something important? Well...while you're here...
3 and 7 look like biggies. I don't know if anyone has mentioned it, but 3 seems to have a somewhat more interesting role in my opinoin. Ever read a fairy tail? Chances are, there will be three of something. Three pigs, Goldilox, etc. i remember finding out the answer to why this is, but I have forgotten it

I guess three is just one of those magical numbers.
For seven, I have nothing more to add, except that, maybe Tolkien wanted his book to get published, so he put little "lucky charms", if you will, throughout his book, to try and make it sell better. Just an guess (and a bad one at that).
I wanna see that 8th Palantir
