I checked out the calculus book on interstate library lone though our local library (this is a new option here now) and I know what happened to Fred’s parents…
His dad was a looser.. drunk all the time. His mother didn’t know anything except how to make cookies. Anyway Fred (at 3 months old) was watching tv on the stock market and make a lot of money on a penny stock. With this money his dad bought a new sky scraper. Then his dad moved them there and then had a diving board at the top of the sky scraper for the pool. Freds mom fell off the diving board and missed the pool and mostly likely, his dad was charged for the murderer…
Then Fred because a math professor.
This was the condensed version but I just wanted to answer my own question for anyone who wanted to know.
