Roman numbers are a kind of number system established by the Romans sometime between 900 BC and 800. They were used throughout Europe back in the day. The Etruscan system of numbering was the basis for establishing Roman numerals.
However, The Hindu-Arabic numerals replaced Roman numerals sometime in the 14th century. Still, Roman numerals continue to be used even to this day.

What are the five laws of writing Roman numerals?
The Roman number system has several rules that must be followed, much like the Hindu-Arabic number system, while writing. Therefore, the five laws of Roman Numerals are:
I. Every time a symbol gets repeated, its value gets added.
Ex: XX = 10+10=20
II. Only I, X, C, and M can get repeated three times in a row. Furthermore, the numbers L, V, and D cannot get repeated. Else, the number becomes invalid.
III. In addition, the digit with the higher value takes the left position to the lower value digit.
IV. For subtraction, the higher value digit comes to the right of the lower value digit.
V. Only the letters I, X and C can get used for subtraction.

Roman Numbers Theory of Origin
Tally stick theory – Shepherds in Rome employed a tally system that relied on sticks. The sheep count was maintained by marking symbols on a stick using a knife. For every one sheep, the shepherds would carve a single notch in the shape of I. The fifth sheep would have a notch in a “V,” and the tenth an “X”.
Hand Signal Theory – This theory states that numbers are represented by how they appear on our hands upon using our fingers.
For example, when we count five on our fingers, our index finger and thumb form the letter V. Similarly, if we count eight on both hands, we will have one open hand, with five open fingers in one hand and three open fingers in the other.
