MATHMATICS-VEDIC HINDUISM

Vedic Hindus knew mathematics much much before the world ...and possibly it all took from here after the Dashrajnya war (Ref. http://shankhnaad.net/index.php/nation/aryavart/99-article-1001)
The fire altars most of them 3000 BCE- 4500 BCE ...show sufficient evidence of mathematical calculations for making havan kund for Vedic offerings - both by presence of private and public fire-altars.
So-called Aryan cultural traits like horses, iron, cattle-rearing or fire worship have been found to be either indigenous developments (like iron) or to have existed in Harappan and pre-Harappan sites (like in case of horses and fire worship). No special Aryan culture in ancient India can be differentiated apart from the indigenous culture. This along with many other scientific, anthropological and archeological evidences slams the ‘Aryan Invasion’ theory right in its face.
