  1. Roman Numerals – History, Rules, and Chart takshilalearning.com/roman-numerals-history-rules-and-chart/ September 13, 2021 What are Roman Numerals? Roman Numerals 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 symbols of the Roman numeral system? Some fundamental Roman numerical symbols include Roman Numbers I V X L C D M Hindu-Arabic Numbers 1 5 10 50 100 500 1000 1/10

  2. Fun Fact: The Roman Numeral System does not contain 0. It is because India’s great mathematician, Aryabhatta, did not invent it till that time. 5 laws of writing Roman numerals 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. Ex: Roman Numbers Valid/Invalid MCXXXXIII Invalid XXII Valid LLXXII Invalid LXI Valid III. In addition, the digit with the higher value takes the left position to the lower value digit. Ex: 10 + 2 = 12 X + II = XII IV. For subtraction, the higher value digit comes to the right of the lower value digit. 2/10

  3. Ex: 10 – 1 = 9 X – I = IX V. Only the letters I, X and C can get used for subtraction. Roman Numerals Chart 1 to 100 What are the roman numerals for 1-100?

Because it is older than the Hindu-Arabic number system, its use has declined. Yet we may still see Roman numerals in everyday life in the following ways: I. Used in the titles of the monarch, queen, and priests. II. Used in the manufacture of clocks and watches. III. Many publications, blogs (such as this one), websites, and other media use it as a number point. IV. The Olympics make significant use of Roman numerals. V. Found on European monuments VI. Used frequently in higher education, particularly in topics like geography, seismology, history, etc. Roman Numbers Theory of Origin I. 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”. II. 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. Now that we know all about the Roman number system, let’s attempt to answer the questions below. 5/10
