Three series expansions for 1/π:
(1) Ramanujan 1, 1914
(2) Ramanujan 2, 1914
(3) Chudnovsky, 1987
These infinite sums are hypergeometric series that converge rapidly to 1/π and have been used for high-precision computation of π

The diagram of the Number System. It accurately maps out how different sets of numbers nest inside one another, starting from the most basic counting numbers all the way up to complex numbers.
