To write XXXIII in Hindu-Arabic numerals, we need to convert each Roman numeral symbol into its corresponding Hindu-Arabic numeral value.

In Roman numerals, X represents the value of 10. Since XXX is equivalent to 3 X’s, it has a value of 10 + 10 + 10, which is equal to 30.

Next, we have the Roman numeral symbol III. Each I has a value of 1, so III has a value of 1 + 1 + 1, which is equal to 3.

To find the Hindu-Arabic numeral equivalent of XXXIII, we simply add the value of each Roman numeral symbol together. Therefore:

XXXIII = XXX + III = 30 + 3 = 33

So, XXXIII in Hindu-Arabic numerals is equal to 33.

## here are a few more ways to convert XXXIII in Roman numerals to Hindu-Arabic numerals:

### Method 1:

Break down the Roman numeral into its component symbols: XXXIII

Convert each symbol to its Hindu-Arabic numeral equivalent: 10 + 10 + 10 + 1 + 1 + 1

Add the values of each symbol: 10 + 10 + 10 + 1 + 1 + 1 = 33

Therefore, XXXIII in Hindu-Arabic numerals is 33.

### Method 2:

Identify the largest Roman numeral symbol in XXXIII, which is X, and convert it to its Hindu-Arabic numeral equivalent: 10.

Subtract X from XXXIII: XXXIII – X = XXIII

Repeat the process with the next largest Roman numeral symbol (also X): XXIII – X = XIII

Finally, convert the remaining Roman numeral symbols to their Hindu-Arabic numeral equivalents: XIII = 10 + 3 = 13

Therefore, XXXIII in Hindu-Arabic numerals is 33.

### Method 3:

Start with the value of the first Roman numeral symbol, X, which is 10.

If the next symbol, also X, has a value greater than or equal to the previous symbol, add it to the total: 10 + 10 = 20.

If the next symbol, I, has a value less than the previous symbol, subtract it from the total: 20 – 1 = 19.

Repeat this process for each subsequent symbol until all symbols have been accounted for: 19 + 1 + 1 + 1 + 1 = 23.

Finally, add the value of the remaining symbols: 23 + 10 = 33.

Therefore, XXXIII in Hindu-Arabic numerals is 33.

## Here are a few examples of mathematical operations using XXXIII:

**Addition:**

- XXXIII + 10 = XLIII
- XXXIII + 20 = LIII
- XXXIII + 5 = XXXVIII

**Subtraction:**

- XXXIII – 10 = XXIII
- XXXIII – 20 is not possible as Roman numerals cannot represent negative numbers
- XXXIII – 5 = XXVIII

**Multiplication:**

- XXXIII x 2 = LXVI
- XXXIII x 3 = XCIX
- XXXIII x 10 = CCCXXX

**Division:**

- XXXIII ÷ 11 is not possible as Roman numerals do not have a representation for fractions or decimals
- XXXIII ÷ 3 = X with a remainder of III
- XXXIII ÷ 9 is not possible as Roman numerals cannot represent fractions or decimals.

Note that in some cases, the result of a mathematical operation may not have a Roman numeral representation.
