Roman numerals are a number system that originated in ancient Rome. Instead of using digits as we do in our regular number system, Roman numerals use letters to represent different values. Each letter has a specific numerical value, and when combined, they create different numbers.

Here’s a short story to understand more about Roman numbers.

Once upon a time, in the ancient city of Rome, there were no numbers like the ones we use today. Instead, the Romans had their own special way of writing numbers called Roman numerals.

A curious Roman child named Marcus, who loves exploring ancient ruins and stumbled upon an old stone tablet with mysterious inscriptions. It turned out to be a guide to understanding Roman numerals.

Marcus learned that there were seven basic symbols used in Roman numerals. These symbols were letters from the Latin alphabet. The symbols and their corresponding values were:

I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1000

• Q-10
• Which Roman numeral represents the number 3000? ## In Roman numerals, each symbol represents a block size, and Marcus used this concept to understand their values. For example, the small block represented by I was worth 1. By placing two small blocks (II) together, he had 2 in total. Marcus then discovered that a bigger block, represented by V, was worth 5. By placing the V block on top of the two small blocks (II), he could represent 7. He also learned that when a smaller symbol appears before a larger symbol, it means subtraction. For instance, IV represents 4, where I (1) is subtracted from V (5). With this understanding, Marcus continued exploring Roman numerals and their significance in ancient Roman culture.In simple words, Roman numerals are a number system that uses letters to represent different values. By combining these letters, we can create different numbers.
