Zero is needed for positional place value purpose and to distinguish for example 27 from 207.
Yes because, without zero there couldn't be any number with a zero in it.
Not necessarily.
we need it for place value
It will be a square matrix and, to that extent, it is diagonalisable. However, the diagonal elements need not be non-zero. It will be a square matrix and, to that extent, it is diagonalisable.

because u have moved the decimal one place therefore you will need to add a zero to fill in the space
they need to train in lots of zero gravity and engineering
There was no zero in ancient Chinese numerals. The ancient Chinese number system was not a positional system, so there was no need for a zero.
Zero.
Zero.
Zero.
If you have the giant red materia than all you need to do is talk to it to get zero.
If the numerator of a fraction is zero, it doesn't need to be converted to a common denominator because its value is actually zero (zero by anything divided is zero), so you should drop it from the equation.
