Roman numerals are a system of numerical notation used in ancient Rome. They are based on the use of the letters of the alphabet, specifically I, V, X, L, C, D, and M, which represent the values 1, 5, 10, 50, 100, 500, and 1000, respectively. To form a number in Roman numerals, the importance of the letters is added together. For example, the number 39 can be represented as XXXIX, 10 + 10 + 10 + 5 + 1 + 1 + 1. There are certain rules to follow when constructing Roman numerals, such as the use of subtractive notation (e.g., IV for 4, XL for 40), and the restriction of repeated use of the same letter (e.g., only three consecutive I's are allowed). Roman numerals are still used today in various applications, such as clock faces, book and chapter numbering, and movie sequels.

The Roman numeral system is a numeral system originating in ancient Rome and was used throughout the Roman kingdom. This chart displays the Roman numerals from 1-100 in a table format for quick reference.

Here is the chart of roman numerals 1 to 100

The Roman numeral system uses symbols to represent numbers, with "I" representing 1, "V" representing 5, "X" representing 10, "L" representing 50, "C" representing 100, and "D" representing 500. The symbols can be combined to represent larger numbers, such as "XLV" for 45 and "XCIX" for 100.

The Roman numeral system represents numbers using symbols, like "I" for 1, "V" for 5, "X" for 10, "L" for 50, "C" for 100, and "D" for 500. Numbers are formed by combining these symbols, for example, "XLV" stands for 45, and "XCIX" represents 99.

1 = I | 2 = II | 3 = III | 4 = IV | 5 = V |

6 = VI | 7 = VII | 8 = VIII | 9 = IX | 10 = X |

76 = LXXVI | 77 = LXXVII | 78 = LXXVIII | 79 = LXXIX | 80 = LXXX |

81 = LXXXI | 82 = LXXXII | 83 = LXXXIII | 84 = LXXXIV | 85 = LXXXV |

86 = LXXXVI | 87 = LXXXVII | 88 = LXXXVIII | 89 = LXXXIX | 90 = XC |

91 = XCI | 92 = XCII | 93 = XCIII | 94 = XCIV | 95 = XCV |

96 = XCVI | 97 = XCVII | 98 = XCVIII | 99 = XCIX | 100 = C |

**Method 1: **

- Start with the symbol for 1 (I), 5 (V), 10 (X), 50 (L), or 100 (C).
- Add or subtract symbols to get to the desired number.
- Use "-" for subtraction (4 is IV, 9 is IX), otherwise add the symbols (6 is VI, 42 is XLII).

**Method 2:**

- Write down the numerals in descending order from left to right, starting with the largest numeral possible.
- Repeat step 1 until the desired number is reached.

**Example:**

To write the number 42 in Roman numerals, starting with 40 (XL), then add 2 (II). So, 42 in Roman numerals is XLII.

The rules for writing Roman numerals from 1 to 100 are as follows:

1- Numerals are written from left to right, with the largest numeral first and the smallest numeral last.

2- When a smaller numeral is placed before a larger numeral, it represents subtraction. For example, the number 4 is written as IV (5 minus 1).

3- The numerals 5 (V) and 10 (X) can never appear more than three times in a row. Instead, the next higher numeral is used to indicate a larger value (e.g. 40 is XL, not XXXX).

4- The numerals 50 (L) and 100 (C) can appear no more than one time in a row.

5- The numeral for 1,000 (M) can appear multiple times in a row to indicate a larger value. By following these rules, Roman numerals can be written accurately and efficiently from 1 to 100.

Here are a few examples of solving Roman numerals:

1- Convert the Roman numeral "XIV" to decimal:

- X = 10, I = 1, V = 5
- In "XIV", X comes first, followed by me and then V. So, we can add the values as 10 + 1 + 5 = 16.
- Therefore, XIV = 16 in decimal.

2- Convert the decimal number "39" to a Roman numeral:

- To represent 39 in Roman numerals, we can use the following symbols: X (10), XXX (30), and IX (9)
- Therefore, 39 in decimal can be written as XXXIX in Roman numerals.

3- Addition of Roman numerals "X" and "V":

- X = 10 and V = 5
- Adding these two numbers, we get 10 + 5 = 15
- To represent 15 in Roman numerals, we can use the symbols: X (10) and V (5)
- Therefore, the sum of X and V is XV in Roman numerals.

In Roman numerals, the largest numeral should always come first and the smaller numeral should come after it. Also, subtractive notation is used to write smaller numbers in Roman numerals.
