Roman Numerals:

Definition:

A unique type of number notation that was once employed by the Romans is known as Roman Numerals. Letters are used to represent specific base numbers and arbitrary numbers in the number system using the Roman numeral, which is an additive and subtractive system.
Roman numerals are represented by a separate set of symbols, some of which are letters from the English alphabet. For instance, the roman numeral for 5 is V. It can be used to name anything, including classes like Class I, Class II, and Class X.

How do Roman numerals work?

The ancient number system known as Roman numerals is still prevalent worldwide. The fixed positive numbers are represented by alphabets in roman numerals. I, II, III, IV, V, VI, VII, VIII, IX, and X are roman numerals that stand for the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 respectively.

The roman numbers XI for 11, XII for 12, XII for 13,... to XX for 20 come after 10. The table below lists the most popular roman numerals currently in use to represent the fundamental numbers.

Roman Letters:

Although not all English alphabets are roman alphabets, the roman letters are. Out of the 26 English alphabets, there are 23 roman alphabets, and J, U, and W are not included. A, B, C, D, E, F, G, H, I, K, L, M, N, O, P, Q, R, S, T, V, X, Y, and Z are the letters in the Roman alphabet. Roman symbols are another name for these roman letters.

For instance, MMXIX is how the year 2019 is written.

Roman numeral Writing Guidelines:

• When writing a number in roman numerals, there are specific criteria that must be adhered to. Please review the following rules.
• As many times as the symbol is repeated, its value is added to itself. (For instance, II-2, XX-20, and XX-30).

• Only three times can a symbol be repeated; for example, XXX = 30, CC = 200, etc.

  The symbols V, L, and D are unique.

• When a symbol with a lower value follows one with a higher value, their values will be added. As an illustration, VI = V + I = 5 + 1 = 6.
• When a symbol with a lower value precedes one with a higher value, the lower value symbol will be removed. As an illustration, IX = X - I = 10 - 1 = 9.
• V, L, and D are never deducted since they are not put before a sign of a higher value.
• Only the symbols V and X can be subtracted from, and only the symbols L, M, and C can be subtracted from, the sign I.

Roman Numeral Conversion to Numbers :

Rule no 1: If one or more symbols are positioned after a letter with a higher value, add that sum.

VII = 7 (5 + 2 = 7)
LXXX = 80 (50 + 10 + 10 + 10 = 80)
MCCC = 1300 (1000+100 + 100 + 100 = 1300)

Rule no 2:Subtract the value of the symbol if it comes before a letter with a higher value.

CM = 900 (1000 - 100 = 900)
IX = 9 (10 - 1 = 9)
XC = 90 (100 - 10 = 90)

Rule no 3:In the case of roman numerals, 1000 is replaced by a bar.

5000	10,000	50,000	100,000	500,000	1,000000
