first of all, i really loved how the maths were written. it makes one view mathematics from a different perspective. the applications of maths (what we are learning today) makes one really despise the subject, not knowing the basics and nature of maths or numbers themselves are fascinating. i swear, the professor is the best professor we'll never have. 

storywise, i love everyone. i adore their relationship dynamics so much. i always melt when the professor talks and teaches root, root's attachment to the professor, and how the professor had such an impact on both root and the housekeeper. It was just so soft and comforting.

my only problem is, i think, the balance between the story and the maths. though, i really love math, and i love reading about them, in this case, i feel like, the maths overlaps the story (or maybe it's just me, OR maybe that's really the author's purpose). i'm also not really a fan of the baseball reference. the mystery about the professor and the sister-in-law was also not  resolved. i'm also not sure if i like the ending. 

overall, it was a very good book. i adore and love it so much
