CMXXVI Roman Numerals
To meet their daily commerce and administration needs, the ancient Romans developed Roman Numerals. It used a combination of seven symbols — I, V, X, L, C, D, and M to represent numbers. Roman numerals were used to record transactions, keep track of data, and label military units. In this topic, we are going to learn about the Roman numeral CMXXVI.
What is CMXXVI in Roman Numerals?
Ancient Romans discovered that counting fingers could get very complicated after 10. So to overcome the complexity, the Roman numeric system was developed. This was widely used throughout Europe as a standard writing system until the late Middle Ages.
Seven symbols are used to represent numbers in the Roman numeric system — I, V, X, L, C, D, and M. The numerals are made up of different combinations of these symbols. CMXXVI in Roman numerals can be written in number form by adding and subtracting the values of each Roman numeral, i.e. CMXXVI = 926.
Let us learn more about the Roman numeral CMXXVI, how we write them, the mistakes we usually make, and ways to avoid these mistakes.
Basic Rules for CMXXVI in Roman Numerals
When writing Roman numerals, there are a few rules that we need to follow based on the Roman numerals we are trying to write. In this section, we will learn about the rules when writing Roman numerals and how to represent them.
Rule 1: Addition Method:
When a larger or equal symbol is followed by a smaller symbol, we add the numerals to each other. For example, in VIII, we have 5 + 3 = 8.
Rule 2: Repetition Method:
A symbol that is repeated three times in continuation increases the value of the numeral. For example, XXX = 30.
Rule 3: Subtraction Method:
We use the subtraction method when a smaller symbol precedes a larger symbol. For example, XL = 40 (which is 50 – 10).
Rule 4: Limitation Rule:
Symbols cannot be repeated more than three times, and some symbols, such as V, L, and D, cannot be repeated more than once. For example, 10 is represented as X and not VV.
How to Write CMXXVI in Roman Numerals?
Let us learn about how to write CMXXVI in Roman numerals. There are two methods that we can use to write Roman numerals:
- By Expansion Method
- By Grouping Method
CMXXVI in Roman Numeral by Expansion Method
The breaking down of Roman numerals into parts and then converting them into numerals is what we call the expansion method. The expansion method involves breaking down Roman numerals into numerical form and adding or subtracting them to get the final number.
Step 1: Break the Roman numerals into parts.
Step 2: Now write each of the Roman numerals with its numerical digit in the place value. Step 3: Add or subtract the numerals together.
For CMXXVI,
Step 1: First, we break the Roman numerals. CMXXVI = C + M + X + X + V + I Step 2: Write the Roman numerals for each part. The Roman Numeral C is 100 The Roman Numeral M is 1000 The Roman Numeral X is 10 The Roman Numeral V is 5 The Roman Numeral I is 1
Step 3: Combine all the numbers considering the subtraction rule. C(100) is subtracted from M(1000) = 900 X(10) + X(10) = 20 V(5) + I(1) = 6 900 + 20 + 6 = 926. Therefore, the Roman Numeral CMXXVI is 926.
CMXXVI in Roman Numeral by Grouping Method
Using subtraction and addition rules, we will apply the grouping method. This means we break the Roman numerals into smaller groups, which makes it easier to work with. This method groups the Roman numerals logically, and then we write the numbers for each group.
Step 1: Take the largest number and write the number for that Roman numeral.
Step 2: Write the Roman numeral using the subtraction and addition rules. Example: Let’s take the Roman numeral CMXXVI.
Step 1: The larger Roman numerals are what we will begin with. Once split, the Roman numerals we get are CM, XX, and VI. The numeral for CM is 900
Step 2: Now we need to either add or subtract the smaller number, depending on its place.
Here we add XX (20) and VI (6) to CM and we will get CMXXVI. The Roman numeral XX is 20 The Roman numeral VI is 6 Therefore, the numeral of CMXXVI is 926.
Numbers Related to CMXXVI in Roman Numerals
We follow a pattern when it comes to writing Roman numerals. In this section, we will write some numbers related to the Roman numeral CMXXVI:
| Roman Numeral | Number | Breakdown |
|---|---|---|
| X | 10 | X |
| XI | 11 | X + I |
| XII | 12 | X + I + I |
| XIII | 13 | X + I + I + I |
| XIV | 14 | X + IV |
| XV | 15 | X + V |
| XVI | 16 | X + V + I |
| XVII | 17 | X + V + I + I |
| XVIII | 18 | X + V + I + I + I |
| XIX | 19 | X + IX |
| CMXXVI | 926 | CM + X + V + I |
Common Mistakes and How to Avoid Them in CMXXVI Roman Numerals
Students can make mistakes when studying Roman numerals. Here are a few common mistakes students make, and ways to avoid them.
Mistake 1
Mistakes when applying the repetition method
It can be quite confusing for beginners to remember that Roman Numerals cannot be repeated more than three times. Another thing to keep in mind is that Roman numerals such as V, L, and D cannot be repeated.
For example, writing LL as 100 is incorrect; the correct answer is C.
CMXXVI Roman Numerals Examples
Problem 1
What is the result of adding CMXXVI to LXX in Roman numerals?
The sum is CMXCVI
Explanation
Convert both Roman numerals into their decimal form:
CMXXVI = 926
LXX = 70
Now add both numbers: 926 + 70 = 996
Now convert the number into its Roman numeral: 996 = 900 (CM) + 90 (XC) + 6 (VI) = CMXCVI
Problem 2
Subtract CCCXX from CMXXVI and express the result in Roman numerals.
The difference is DCVI
Explanation
Convert the Roman numerals into their decimal form:
CMXXVI = 926
CCCXX = 320
Now we subtract the numbers: 926 - 320 = 606
Convert the number into its Roman numeral: 606 = 600 (DC) + 6 (VI) = DCVI
Problem 3
Divide CMXXVI by 3 and provide the answer in Roman numerals.
CCCVIII
Explanation
Convert CMXXVI into its decimal form:
CMXXVI = 926
Divide by 3: 926 ÷ 3 = 308
Write 308 in Roman numerals: 308 = 300 (CCC) + 8 (VIII) = CCCVIII
Problem 4
Find the product of CMXXVI and II.
MDCCCLII
Explanation
Write CMXXVI and II in numbers:
CMXXVI = 926
II = 2
Multiply the numbers: 926 × 2 = 1852
Convert 1852 into its Roman numerals: 1000 (M) + 800 (DCCC) + 50 (L) + 2 (II) = MDCCCLII
Problem 5
Convert CMXXVI into its decimal form.
In decimal form, CMXXVI is 926
Explanation
Break CMXXVI into components:
CM = 900
XX = 20
VI = 6
Add values: 900 + 20 + 6 = 926
