<p>There are certain basic rules to write a<a>number</a>in Roman Numerals. In this section, let’s discuss some basic rules that need to be remembered when writing a number in Roman numerals.</p>
10
-
<h3><strong>Rule 1: Addition Method</strong></h3>
11
-
<p>The<a>addition</a>method is used when a smaller number is placed after a larger number. For example, VI → V + I → 5 + 1 = 6</p>
12
-
<h3><strong>Rule 2: Repetition Method</strong></h3>
13
-
<p>To write a large number, certain Roman Numerals can be repeated up to three times. III → 3.</p>
14
-
<h3><strong>Rule 3: Subtraction Method</strong></h3>
15
-
<p>If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the larger number. For example, IX → X - I → 10 - 1 = 9</p>
16
-
<h3><strong>Rule 4: Limitation Rule</strong></h3>
17
-
<p>Symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we don't write VV for 10; instead, we use X, and we write 8 as VIII, not IIIIIIII.</p>

<h2>1966 in Roman Numerals by Expansion Method</h2>
25
-
<p>In the expansion method, based on the<a>place value</a>, the number is broken down. In this section, we will learn how to write 1966 in Roman numerals using the expansion method. To write 1966 in Roman Numerals, follow these steps:</p>
26
-
<p><strong>Step 1:</strong>Break the number based on place value, such as ones, tens, hundreds, etc. For 1966, we write it as 1000 + 900 + 60 + 6</p>
27
-
<p><strong>Step 2:</strong>Convert each number into Roman Numerals</p>
28
-
<ul><li>1000 in Roman Numerals - M</li>
29
-
</ul><ul><li>900 in Roman Numerals - CM</li>
30
-
</ul><ul><li>60 in Roman Numerals - LX</li>
31
-
</ul><ul><li>6 in Roman Numerals - VI</li>
32
-
</ul><p><strong>Step 3:</strong>Combine the Roman Numerals together. Therefore, 1966 in Roman Numerals is M (1000) + CM (900) + LX (60) + VI (6) = MCMLXVI</p>
33
-
<h2>1966 in Roman Numerals by Grouping Method</h2>
34
-
<p>When writing a large number into Roman Numerals, we group the number. To write 1966 in Roman Numerals, we group 1966 as 1000 + 900 + 60 + 6</p>
35
-
<ul><li>1000 in Roman Numerals - M</li>
36
-
</ul><ul><li>900 in Roman Numerals - CM</li>
37
-
</ul><ul><li>60 in Roman Numerals - LX</li>
38
-
</ul><ul><li>6 in Roman Numerals - VI</li>
39
-
</ul><p>So, 1966 is written as MCMLXVI in Roman Numerals.</p>

<h3>Problem 1</h3>
43
-
<p>Calculate the sum of MCM and LXVI.</p>
44
-
<p>Okay, lets begin</p>
45
-
<p>The sum of MCM and LXVI is MCMLXVI.</p>
46
-
<h3>Explanation</h3>
47
-
<p>To find the sum, we add the two Roman numerals together.</p>
48
-
<p>MCM = 1900</p>
49
-
<p>LXVI = 66</p>
50
-
<p>1900 + 66 = 1966</p>
51
-
<p>1966 in Roman Numerals can be written as MCMLXVI.</p>
52
-
<p>Well explained 👍</p>
53
-
<h3>Problem 2</h3>
54
-
<p>A historian is categorizing MCMXCVI artifacts into LXVI categories. How many artifacts will each category have?</p>
55
-
<p>Okay, lets begin</p>
56
-
<p>Each category will have XXX artifacts.</p>
57
-
<h3>Explanation</h3>
58
-
<p>To find the number of artifacts per category, we divide the total number of artifacts by the number of categories.</p>
59
-
<p>MCMXCVI = 1996</p>
60
-
<p>LXVI = 66</p>
61
-
<p>1996 / 66 ≈ 30</p>
62
-
<p>30 in Roman Numerals can be written as XXX.</p>
63
-
<p>Well explained 👍</p>
64
-
<h3>Problem 3</h3>
65
-
<p>If a library has MCMXL books and receives an additional XXVI books, how many books does it have now?</p>
66
-
<p>Okay, lets begin</p>
67
-
<p>The library now has MCMXLXVI books.</p>
68
-
<h3>Explanation</h3>
69
-
<p>To find the new total, we add the two numbers together.</p>
70
-
<p>MCMXL = 1940</p>
71
-
<p>XXVI = 26</p>
72
-
<p>1940 + 26 = 1966</p>
73
-
<p>1966 in Roman Numerals is MCMLXVI.</p>
74
-
<p>Well explained 👍</p>
75
-
<h3>Problem 4</h3>
76
-
<p>What is the difference between MM and XXXIV?</p>
77
-
<p>Okay, lets begin</p>
78
-
<p>The difference between MM and XXXIV is MCMXLVI.</p>
79
-
<h3>Explanation</h3>
80
-
<p>The difference of two numbers is the value we get when subtracting the smaller number from the larger number.</p>
81
-
<p>MM = 2000</p>
82
-
<p>XXXIV = 34</p>
83
-
<p>2000 - 34 = 1966</p>
84
-
<p>1966 in Roman Numerals can be written as MCMLXVI.</p>
85
-
<p>Well explained 👍</p>

<h3>Problem 5</h3>
87
-
<p>Convert the sum of 950 + 1016 into Roman numerals using the expansion method.</p>
88

<p>Okay, lets begin</p>
89
-
<p>The sum of 950 + 1016 is MCMLXVI.</p>
90
-
<h3>Explanation</h3>
91
-
<p>Step 1: First convert the numbers 950 and 1016 into Roman numerals 950 - CML 1016 - MXVI</p>
92
-
<p>Add the numbers together: 950 + 1016 = 1966 Using expansion method: 1966 = 1000 + 900 + 60 + 6 = MCMLXVI.</p>
