Question

Answer 1

Now, if we only knew which math book! (There are quite a few out there.)

 

Warning: predictions are guesses masquerading in math costumes. Phony; unreliable.  A recent notable failure occurred last November. A lot of people made a lot of money in the "Campaign 2016" that went on for one interminable year, and which ended in complete disaster for the favorite. We now live in an Alternative Fact World with an unstable Fakir-in-Chief.
