The Roman system started in around 400 BC but the system we use today didn't arrive until the 1st century AD (albeit without subtractive notation such as IV). There have been other numeral systems, including positional notation systems…

### Why were roman numerals changed to Arabic numerals?

Roman numerals weren't changed to Hindu-Arabic numerals. The two systems developed separately around the same time period. Roman numerals were in common use long after the Roman empire collapsed in the west, right up until the 14th century, by which time the Indian base-9 positional system had evolved into a base-10 positional system and was brought to Europe by the Arabs (the system itself is not Arabic, but Indian). Mathematicians immediately took to the much…

### What is 12345678998765432 in Roman Numerals?

The above number can quite easily be converted into Roman numerals through a system of brackets and superscripts in a similar way that we use exponents to increase the value of our numbers today as for example take the value of the first two digits when converted into Roman numerals they are as follows:- (((MCC)))(((M))) = 12,000,000,000,000,000 = 1.2*1016 in scientific notation But in practice the ancient Romans had little need for such large numbers…

However, the Roman system has limitations - there are only so many numbers that can be written…

### What are positional muber system?

I think you meant positional number system or Positional Notation. In computer science when we talk about positional notation where talking about the binary(base 2) and hexadecimal(base 16) system. So for the most part a positional number system is a counting system. We for example use a base 10 counting system.

### What notation system replaced roman numerals and why did it replace roman numerals?

Systems which use abbreviations for repetitions of symbols (e.g. Hieratic numerals, Chinese numerals). Then that was replaced with the Hindu-Arabic numeral system (0,1, 2, 3, 4, 5, 6, 7, 8, 9 ...... the system we use today) superceded the Roman numeral system because the four operations of arithmetic was easier to work out i.e. addition, subtraction, division and multiplication. A nought figure was incorporated into the Hindu-Arabic system of counting which made the positional place…

### What is Hindu Arabic numerals of 74?

74 is the Hindu-Arabic representation of the number seventy-four. The term Hindu-Arabic defines the system, not the symbols; the symbols are independent of the system.
