The higher arithmetic

The higher arithmetc begins with some innocently simple questions about the natural numbers 1, 2, 3, etc. Then things become difficult in a hurry. Take the question about how many primes there are less than a given number. No one has answered it to everyone's satisfaction.

Life would be much duller if it was not that way.
