Mathematics

This one began with the leftover cricut cutouts from 5, which you will find here.
Then i looked for a quote about mathematics to be on the opposite side. 
I have gifted it to my friend Marian, for her birthday today. We’re seeing Hamilton and eating dinner together tonight!
The box is my Samsung 21 phone box, the piece was tailored to fit inside. 
it measures around 6.5 x 14 cm and is about 2.5 cm deep (i’m making that number up, it’s never going to be exhibited anywhere, and dimensions only matter when you’re posting it, right?).
Like 5, the cutouts come from a book called One.
