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.
Though you may have learned about Roman numerals in school and how they came about, we doubt you knew that the numerals were used for addition or subtraction, aside from being used as a numerical system.
Try your hand at this Ancient Roman math quiz and see how well you know your Roman numerals. Only 12 percent of people who take the math test typically pass it, so if you don't get it right the first time, it's OK. Plus, not all of us can be good at math, whether it's with numerals or natural numbers we learned in math class.
Be sure to share this math test with friends and loved ones who you think would get a kick out of this fun brain teaser.
