What is the following in Arabic numbers xix?

The Roman numeral 'xix' represents the number 19 in Arabic numerals. Roman numerals are based on specific letters that correspond to values: 'x' stands for 10, 'i' represents 1, and 'v' represents 5.

In 'xix', the first 'x' is 10, and the 'i' before the second 'x' indicates that we need to subtract 1 from the value of the following 'x'. Thus, we evaluate it as follows:

• The first 'x' equals 10.

• The 'i' represents 1, and it implies you subtract this from the next 'x'.

• The second 'x' also equals 10.

Putting this all together:

10 (from the first 'x') + 10 (from the second 'x') - 1 (from 'i') = 19.

This confirms that 'xix' translates to 19 in Arabic numerals.
