For x > 1 let π 0 (x) = π(x) − 1 / 2 when x is a prime number, and π 0 (x) = π(x) otherwise. Bernhard Riemann, in his work On the Number of Primes Less Than a Given Magnitude, proved that π 0 (x) is equal to [9] Riemann's explicit formula using the first 200 non-trivial zeros of the zeta function
A method analogous to piece-wise linear approximation but using only arithmetic instead of algebraic equations, uses the multiplication tables in reverse: the square root of a number between 1 and 100 is between 1 and 10, so if we know 25 is a perfect square (5 × 5), and 36 is a perfect square (6 × 6), then the square root of a number greater than or equal to 25 but less than 36, begins with ...

It does not apply to organellar genomes (mitochondria and plastids) smaller than ~20–30 kbp, nor does it apply to single stranded DNA (viral) genomes or any type of RNA genome. The basis for this rule is still under investigation, although genome size may play a role. Histogram showing how 20309 chromosomes adhere to Chargaff's second parity rule
