# Why did the Romans use Roman numerals?

Roman numerals were the symbols developed by the Ancient Romans for counting and other numbering activities. The Romans used them because they developed them and that was what… they knew.

Roman numerals are suitable for carving foundation years into stone, but they are not well suited for doing mathematical calculations. Addition can be done with …Roman numeral with a reasonable amount of effort if you are adding only two or three small numbers together. Subtraction is much more difficult and multiplication and division are almost impossible. The higher forms of mathematics, such as algebra, calculus, statistics, numerical analysis, topology, etc, could not have even been invented if Roman numerals were all we had. Roman numerals are still used today to some extent but they were replaced by the Hindu-Arabic numeral system during the Middle Ages whose numerals we still use today which are 0 1 2 3 4 5 6 7 8 and 9.

# Why don't you use roman numbers always?

Although the Romans were very clever - they gave us central heating, democracy, road systems, fast food outlets and a host of other 'modern' things - there weren't a pat…ch on the Greeks or Arabs when it came to mathematics (or, in the case of the Greeks, geometry). The problem was that their number system was very complex. based on 5s, rather than have 9 symbols and a zero as we do, and a decimal placement system as we now have, they had a complex system of using letters I, V, X, L, C, D, and M for 1,5,10,50,100,500 and 1000, with complex rules about the writing the numbers in between. They also had no symbol for zero (this was invented by the Arabs). So, when doing arithmentic, Roman numbers were cumbersome and even simple arithmetic was very difficult. When we adopted thhe Arabic system of numbers from 1 to 10, and a zero, with the 1 representing 1, 10, 100, 1000 etc depending upon its position, then arithmetic became very straightforward. So we still use Roman numbers today for simple counting (like on clock faces, or items in a list - (i), (ii), (iii), (iv) etc) but we cannot use Roman numbers when we need to do any arithmetic or more complex mathematics. So that is why the Arabic system has been adopted, not only in the Western world but virtually worldwide.
