As humans evolved over time into the thoughtful, conscious beings that we are today, methods of communicating became of the utmost importance. First, spoken language was developed as a means of verbally articulating one's thoughts and feelings.
Slowly over the course of time, mankind began to use symbols and signs on parchment and stone tablets to keep records of shop inventories and livestock.
Many of the first ever discovered examples of human writing have come in the form of businesses trying to keep their goods organized.
The Roman Empire would become one of the biggest and most powerful civilizations to have graced the Earth before its spectacular failing. They had a robust economy and were active traders. And they needed a way to keep track of numbers.
So, they devised a system that has lasted the test of time and that is still used on special occasions today: the Roman numerals.
Perhaps the most interesting part of Roman numerals is that they're a numbering system similar to the Arabic numerals used around the world today, but with one key difference: the placement of the numeral can indicate either subtraction or addition.
