### Re: Question

it is a ten based number system.when you multiply by ten you get a zero on the right side.when you divide by ten you get a zero on the left side.when there is no point a zero on the left side is valueless.but,when there is, it is not.

\[\sum_{k=0}^{n-1}e^{\frac{2 \pi i k}{n}}=0\]

@Dipan,

suppose you have got $x$. now what would be $x \times 10$?

its $10x+0$. this the $0$ i am talking about which will be the একক স্থানীয় অঙ্ক (i don't know the translation )
