Hint: For some of the problems, we figure you’ll look up a term mentioned in the problem and learn something new. For example, for January 1, you could google "prime-counting function" and go to wikipedia which will help you solve the problem.
Hint: The "..." means "and so on" in math. The problem contains continued fractions with alternating 8 and 9’s. You can learn more about continued fractions here
Hint: There is only one possible digit A can be. Otherwise the result of the multiplication would have 7 digits instead of 6.
