Answer:
Positional
Number System:
In positional number system, there are
only a few symbols called digits, and these symbols represent different values
depending on the position they occupy in the number. The value of each digit in
such a number is determined by three considerations__
1. The
digit.
2. The
position of the digit in the number.
3. The
base of the number system.
In the non-positional number systems,
the characters used are I for 1, II for 2, etc, and are of position invariant,
i.e. each symbol represents the same value regardless of its position in the
number. Since it is very difficult to perform arithmetic calculations with such
a number system, positional number system were developed.
