Key Topics to Revise

1

Basic Roman Numerals and Their Values

  • There are only 7 letters used in Roman numerals: I, V, X, L, C, D, and M.
  • Each letter stands for a fixed number.
  • There is no symbol for zero in Roman numerals.
2

Rules for Reading and Writing Roman Numerals

  • Rule 1: Repeating a symbol adds its value. For example, II = 2, XXX = 30.
  • Only I, X, C, and M can be repeated. V, L, and D are never repeated.
  • A symbol can be repeated only up to three times. So III = 3, but 4 is not IIII.
3

Roman Numerals from 1 to 50

  • Learn the numbers from 1 to 50 in Roman numerals.
  • Special cases: 4 = IV, 9 = IX, 40 = XL, 49 = XLIX.
  • Numbers like 14 = 10 + 4 = X + IV = XIV.
