WebPrime number theorem. One of the supreme achievements of 19th-century mathematics was the prime number theorem, and it is worth a brief digression. To begin, designate the number of primes less than or equal to n by π ( n ). Thus π (10) = 4 because 2, 3, 5, and 7 are the four primes not exceeding 10. Similarly π (25) = 9 and π (100) = 25.
