• X = 10

• L = 50

• C = 100

Roman Numerals Close to XVII

To understand Roman number 17 in a better way, let’s  look at the numbers just before and after it. These nearby Roman numerals show how the system builds numbers by adding letters together.

• 11 is written as XI

• 12 is written as XII

• 13 is written as XIII

• 14 is written as XIV

• 15 is written as XV

• 16 is written as XVI

• 17 is written as XVII

• 18 is written as XVIII

• 19 is written as XIX

• 20 is written as XX

You can see a clear pattern. Starting from X = 10, the numbers grow by adding one or more I’s. For example, XI is 10 + 1, XII is 10 + 2, and XIII is 10 + 3. 

Then, XIV represents 14 using subtraction (10 + 5 - 1). From there, the numbers continue using combinations of X, V, and I to reach XX for 20.

Roman Numerals Rules

Roman numerals follow a few simple rules that make it easier to write and read numbers correctly. These rules are especially helpful when working with numbers like Roman numeral XVII, which stands for 17.

• If a larger Roman numeral is followed by a smaller one, their values are combined through addition.
  This is the most common rule. For example, in XV, the letter X stands for 10 and V stands for 5.Since V comes after X, you add them.

                  So, XV = 10 + 5 = 15

• If a smaller numeral appears before a larger one, its value is subtracted from the larger.
  This rule is used to avoid repeating the same letter too many times. For example, in IV, I comes before V. Since the digit 1 is smaller than digit 5, you subtract:

              IV = 5 - 1 = 4

• The same symbol should not be repeated more than three times in a row.
  For example, III = 3 is correct, but writing IIII for 4 is not allowed. Instead, the number 4 is written as IV by applying the subtraction rule.

• In most cases, letters are written from largest to smallest.
  This helps keep the number clear and easy to read. For example, in XVII, the letters are arranged as X (10), V (5), and I (1) twice.

 All are written in order from largest to smallest, so we simply add them i.e. 10 + 5 + 1 + 1 = 17

Following these rules helps you understand how to read and write Roman numerals correctly. That is why XVII is the correct way to write the number 17 in Roman numerals.

Roman Numerals XVII Examples

Let us try some examples using roman numeral XVII.

Example 1: Add XVII and XV

Solution:

Step 1: Write the values of the Roman numerals in regular numbers.

XVII = 17

XV = 15

Step 2: Add the two numbers.

 17 + 15 = 32

Step 3: Write the answer in Roman numerals.

To write 32 in Roman numerals, we break it down:

30 = XXX (10 + 10 + 10)

2 = II (1 + 1)

So, 32 = XXXII

Example 2: Subtract XII from XVII

Step 1: Convert the Roman numerals to regular numbers.

XVII = 17

XII = 12

Step 2: Subtract the values.

17 - 12 = 5

Step 3: Write the result as a Roman numeral.

5 in Roman numerals is V

Example 3: Multiply XVII by II

Step 1: Convert the Roman numerals to regular numbers.

XVII = 17

II = 2

Step 2: Multiply the values.

17 × 2 = 34

Step 3: Convert the result back to Roman numerals.
To write 34 in Roman numerals:

30 = XXX

4 = IV

So, 34 = XXXIV

Example 4: Divide XVII by V

Step 1: Convert the Roman numerals to regular numbers.

XVII = 17

V = 5

Step 2: Divide the values.

 17 ÷ 5 = 3 with a remainder of 2

Step 3: Convert the result and remainder into Roman numerals.
3 = III
2 = II

So, XVII ÷ V = 3 remainder 2, or in Roman numerals  III remainder II
