Is the Roman numeral a place value system why?
There is no place value system in Roman numerals because they had no numeral for zero. We add a zero to change a 1 to a 10 and then add another 0 to change it to 100 and so on. The Roman system simply used different symbols to change from units to tens and so on. So... I = 1, X = 10, C = 100 and so on, without the need for a change of place or the use of a zero.
Did Romans have a zero in their numeral system?
Yes the Romans had a symbol for zero which was N but there was no need to use it because the positional place value of Roman numerals are self explanatory. For example to write out 501 we need to include a zero to represent its real value but the equivalent of 501 in Roman numerals is DI which does not require a zero symbol.
What is one advantage of using the Roman numeral system?
The Roman numeral system doesn't need a zero symbol for positional place value purposes because the positional place values of its numerals are self evident
In Greek numerals is there a symbol for zero?
No, the Ancient Greek number system did not use zero as a place value, or number for that matter.
What are the two legacies of Indian Mathematics?
The zero symbol and positional place value system of numbers.
