I guess you are asking about ancient Egyptian numbers. They did not use a "place value" numeric system, which is why they had no need for a "zero" in their numbers.
Think about the modern European/American system: starting from the right, the columns indicate units, then tens, then hundreds, then thousands and so on, but always using the same set of numbers from 0 to 9 no matter which column you look at.
The ancient Egyptians used completely differenthieroglyphs to indicate units (1 to 9), tens, hundreds, thousands; their numbers could be written from right to left, or left to right, or vertically downwards - and still mean exactly the same numeric value. For us, 15769 is not the same thing as 96751, but in the Egyptian system the "1" would always mean 10,000, the "5" would always mean 5,000 and so on, because of the signs used to write them.
Because they didn't create it that way. There is no real reason they need one. I guess they decided they didn't want one or didn't think about that idea yet. There is no place value system in roman numerals because they had numeral for zero.
The Romans themselves didn't encounter any problems with their counting system which was in use for over a thousand years. It only is today that people have problems with the Roman numeral system because it doesn't contain a nought figure for positional place value purposes but the positional place value of these numerals are self evident so a nought figure is not needed.
Yes the Romans did have a symbol for zero and it looked like the letter N but they didn't need it in their numeral system for positional place value purposes because the positional place value of Roman numerals are self evident.

It is a system based on the place value.
A nought symbol because it's not needed in the Roman numeral system because the place value of Roman numerals are self evident. But a nought symbol is essential in the Hindu-Arabic numeral system for positional place value purposes.
In the Hindu-Arabic numeral system it is essential for positional place value purposes as it tells us as for example that there is a difference between 27 and 207 but in the Roman numeral system it is not needed because the positional place value of its numerals are self evident.
The defining property of the decimal number system is that the place value of each digit is ten times the place value of the digit to its right.
No, the Roman numeral system is not a place value system. In the Roman numeral system, each individual symbol represents a specific value, and there is no concept of place value. Place value systems, such as the decimal system, rely on the position of digits within a number to determine their value.
Place value is not used in the Roman numeral system.
No
The place value of Roman numerals are self evident that's why the system doesn't need a zero figure for positional place value purposes which is essential in the Hindu-Arabic numeral system.
The standard numeration system used by people is based on counting in tens and powers of ten. The decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. The word decimal, with the prefix deci- refers to ten.
Yes but unlike the Hindu-Arabic numeral system which requires a 0 symbol for positional place value purposes the Roman numeral system does not need a 0 symbol because the positional place value of these numerals are self evident.
Yes and a nought figure is not needed to represent the positional place value of Roman numerals because their positional place values are self evident.
Yes and unlike the Hindu-Arabic numeral system a nought figure is not required for place value purposes because the place value of Roman numerals are self evident.
It is O because it's not needed in the Roman numeral system for place value purposes as the place value of the numerals are self evident
