The ancient numericals of Sanskrit, their Roman & Persian version, which were copied, used in almost all human languages. READ these carefully and learn something before we start our voyage of knowing into the erased past and remove your dark ignorance. ALL your languages numericals & a large vocabulary are based on the foundations of Sanskrit's vast linguistic tree.
Entire Numerical system was loaned by "Arabs" from Sanskrit - a root language, before that Persians used it fo...r 4000 years who loaned their knowledge to Arabs; later on, Roman numbers were replaced by "Hindu" or Sanskrit numbers but Europeans call them Arabic numericals in their zeal to suppress ancient glorious civilization.
