Roman Numerals 1 to 20

The numerals from 1 to 20 are represented as I (1), II (2), III (3), IV (4), V (5), VI (6), VII (7), VIII (8), IX (9), X (10), XI (11), XII (12), XIII (13), XIV (14), XV (15), XVI (16), XVII (17), XVIII (18), XIX (19), and XX (20).

The system has clear rules: numbers are created by arranging letters, placing smaller values before larger ones to indicate subtraction (like IV for 4) and after larger ones for addition (like VI for 6). This numeral system is still in use today in places such as clocks, books, and historical contexts.

Explanation: 1 to 20 table of Roman Numerals

• 1. I – Represents the number 1, and forms the foundation for larger numerals.
• 2. II – Represents 2, formed by placing two "I"s together, as the Roman system is additive up to three.
• 3. III – Represents 3, with three "I"s added together.
• 4. IV – Represents 4, using the subtractive form, where "I" is placed before "V" (5), meaning 1 less than 5.
• 5. V – Represents 5, a base numeral. The "V" likely originates from a hand symbol for five fingers.
• 6. VI – Represents 6, by adding "I" (1) to "V" (5).
• 7. VII – Represents 7, with two "I"s added to "V" (5).
• 8. VIII – Represents 8, using three "I"s added to "V" (5).
• 9. IX – Represents 9, using the subtractive form where "I" is placed before "X" (10), indicating 1 less than 10.
• 10. X – Represents 10, a key base numeral in the Roman system, from which higher numbers are constructed.
• 11. XI – Represents 11, by adding "I" (1) to "X" (10).
• 12. XII – Represents 12, by adding two "I"s to "X" (10).
• 13. XIII – Represents 13, with three "I"s added to "X" (10).
• 14. XIV – Represents 14, using the subtractive form, where "I" is placed before "V" (5) to indicate 1 less than 15.
• 15. XV – Represents 15, with "V" (5) added to "X" (10).
• 16. XVI – Represents 16, by adding "I" (1) to "XV" (15).
• 17. XVII – Represents 17, with two "I"s added to "XV" (15).
• 18. XVIII – Represents 18, with three "I"s added to "XV" (15).
• 19. XIX – Represents 19, using the subtractive form, where "I" is placed before "X" (10), indicating 1 less than 20.
• 20. XX – Represents 20, by adding two "X"s together, following the base 10 principle in Roman numerals.

Roman numerals combine additive and subtractive principles. Numbers like 4, 9, 14, and 19 use subtraction, while others use addition. This numbering system remains in use today, often seen in book chapters, clock faces, movie sequels, and formal numbering.
