MXXXIII 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 MXXXIII.
What is MXXXIII 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. MXXXIII in Roman numerals can be written in number form by adding the values of each Roman numeral, i.e. MXXXIII = 1033.
Let us learn more about the Roman numeral MXXXIII, how we write them, the mistakes we usually make, and ways to avoid these mistakes.

Basic Rules for MXXXIII 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 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 larger symbol follows a smaller 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 MXXXIII in Roman Numerals?
Let us learn about how to write MXXXIII in Roman numerals. There are two methods that we can use to write Roman numerals:
- By Expansion Method
- By Grouping Method
MXXXIII 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 is the breaking down of Roman numerals into numerical form and adding 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 the numerals together. For MXXXIII,
Step 1: First we break the Roman numerals. MXXXIII = M + X + X + X + I + I + I
Step 2: Write the Roman Numerals for each part The Roman Numeral M is 1000 The Roman Numeral X is 10 The Roman Numeral I is 1
Step 3: Combine all the numbers M + X + X + X + I + I + I = 1000 + 10 + 10 + 10 + 1 + 1 + 1 = 1033. Therefore, the Roman Numeral MXXXIII is 1033.
MXXXIII 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 MXXXIII.
Step 1: The larger Roman numerals are what we will begin with. Once split, the Roman numerals we get are M, XXX, and III. The numeral for M is 1000
Step 2: Now we need to either add or subtract the smaller number, depending on its place. Here we add XXX and III to M and we will get MXXXIII. The Roman numeral XXX is 30 The Roman numeral III is 3 Therefore, the numeral of MXXXIII is 1033.
Numbers Related to MXXXIII 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 MXXXIII:
| Number | Roman Numeral | Breakdown |
|---|---|---|
| 1030 | MXXX | 1000 + 30 = 1030 |
| 1031 | MXXXI | 1000 + 30 + 1 = 1031 |
| 1032 | MXXXII | 1000 + 30 + 2 = 1032 |
| 1033 | MXXXIII | 1000 + 30 + 3 = 1033 |
| 1034 | MXXXIV | 1000 + 30 + 4 = 1034 |
| 1035 | MXXXV | 1000 + 30 + 5 = 1035 |
| 1036 | MXXXVI | 1000 + 30 + 6 = 1036 |
| 1037 | MXXXVII | 1000 + 30 + 7 = 1037 |
| 1038 | MXXXVIII | 1000 + 30 + 8 = 1038 |
| 1039 | MXXXIX | 1000 + 30 + 9 = 1039 |
Common Mistakes and How to Avoid Them in MXXXIII 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.
Mistake 2
Not subtracting the numerals correctly
The subtraction method is used when a smaller symbol follows a larger symbol. One should also remember that only specific symbols can be subtracted, like I and X.
For example, IC instead of XCIX for the number 99.
Mistake 3
Not grouping the numbers correctly.
When writing Roman numerals, we need to group the numbers correctly.
For example, the number 15, 10(X) + 5(V).
Mistake 4
Confusing similar-looking symbols for other numbers
Certain numerals have different numbers when placed in a different order. So we must make sure to fully understand the order of certain symbols and their placements. All symbols have to be placed in a different order to represent the correct number.
For example, IV(4) and VI (6) have the same symbols but are in different orders.
Mistake 5
Not counting all numbers when writing in Roman numerals.
Forgetting to count all numbers, when doing the expansion method or grouping method, can lead to mistakes.
For example, writing MXXX (1030) and forgetting III (3) for 1033.
Recheck steps once done during any arithmetic operation.

MXXXIII Roman Numerals Examples
Problem 1
If the year is written as MXXXIII in Roman numerals, what is the year in decimal form?
The year MXXXIII in decimal form is 1033.
Explanation
Break down MXXXIII into its components: M = 1000
XXX = 30 (X + X + X)
III = 3 (I + I + I)
Add these values together: 1000 + 30 + 3 = 1033
Problem 2
A historian finds a manuscript dated MXXXIII. If the manuscript was written 200 years after another document dated DCCCXXXIII, what is the year of the earlier document in decimal form?
The earlier document was dated 833 in decimal form.
Explanation
Convert both Roman numerals into decimal form: MXXXIII = 1033
DCCCXXXIII = 833
Since MXXXIII is 200 years after DCCCXXXIII, the calculation is: 1033 - 200 = 833
Problem 3
A treasure map shows a path 1033 paces long, written as MXXXIII in Roman numerals. If a pirate walks half the distance, how many paces has he walked, in Roman numerals?
The pirate has walked D XVI paces.
Explanation
Convert MXXXIII into decimal: MXXXIII = 1033
Half of 1033 is: 1033 / 2 = 516.5
Since we cannot have half paces, round 516.5 to the nearest whole number: 516
Convert 516 into Roman numerals: 500 (D) + 10 (X) + 6 (VI) = D XVI
Problem 4
A scholar needs to convert a document total of MXXXIII pages into stacks of C pages each. How many full stacks can the scholar create, and how many pages will remain?
The scholar can create 10 full stacks with 33 pages remaining.
Explanation
Convert MXXXIII into decimal: MXXXIII = 1033
Divide by C (100): 1033 / 100 = 10 full stacks with a remainder of 33 pages
Convert the remainder into Roman numerals: 33 = 30 (XXX) + 3 (III) = XXXIII
Problem 5
A clockmaker crafts a clock face with MXXXIII as the total number of hours it can display. If the clock runs for L hours, how many complete cycles does it make, and how many hours are left over?
The clock makes 20 complete cycles with 33 hours remaining.
Explanation
Convert MXXXIII and L into decimal: MXXXIII = 1033
L = 50
Divide 1033 by 50 to find complete cycles: 1033 / 50 = 20 cycles with a remainder of 33
Convert the remainder into Roman numerals: 33 = 30 (XXX) + 3 (III) = XXXIII
