> Caroline's dad is an MIT econ prof and wrote a series of books titled Hard Math for X

He wrote them for caroline and her sister when they were in elementary school, because they excelled in math and wanted more of a challenge.

I bought these books after reading about her when this first started happening a few weeks ago.

No joke, those books are really tough. They are for elementary and middle schoolers, aannnndddd I can't get thru them. lol
