In mathematics education, ethnomathematics is the study of the relationship between mathematics and culture. [1] Often associated with "cultures without written expression", [2] it may also be defined as "the mathematics which is practised among identifiable cultural groups". [3]
Neptune (Latin: Neptūnus [nɛpˈtuːnʊs]) is the god of freshwater and the sea in the Roman religion. [1] He is the counterpart of the Greek god Poseidon.

(The Kerala school did not use the "factorial" symbolism.) The Kerala school made use of the rectification (computation of length) of the arc of a circle to give a proof of these results. (The later method of Leibniz, using quadrature (i.e. computation of area under the arc of the circle), was not yet developed.) [1] They also made use of the series expansion of to obtain an infinite ...
