    might help.

    Think of Roman way of counting.
    Think of Arabic/ Indic way of counting
    Think of hexadecimal counting.

    This page uses hexadecial
    You can tranlate (convert this to decimal ie, Arabi/Indic as world knows it)

    Hope this makes sense.

    ex Tamil K (Ka) = Hexadecimal "0b85" = Decimal "2949"
    Hex is another language in counting system.
