SummaryIn this article I will talk about Roman numerals, a system that began to appear in the early 500 BC. This system consists of symbols used to represent different numbers, most of these symbols have a meaning behind it has to do with the use of the hands. Just as we have rules in our system, they also had their own rules that had to be followed. They developed a way of writing numbers larger by placing bars in different places when writing a number, this meant the number was multiplied by a certain amount. Addition and subtraction is a method like we use today, but they had their own way of solving it. Roman numerals did not include a zero in their system because it was apparently not necessary. Roman numerals began to appear in the early 500 BC. This system was developed to communicate.

Every time we need to know the time, we turn and we can see an analog clock with Roman numerals. We find them in textbooks because the information we read is categorized and the same way on a test with multiple questions. When we watch TV, they appear at the end of a movie or TV show. We even see them in sports like the Super Bowl..
