Answer 2

The above mathematical conundrum can be proved by using the Roman numerals.

Mathematically we know that the following equation  $19-1=20$ is not correct.

But if we convert the equation into Roman numerals then we can solve this equation.

19 written as roman numerals is  "XIX" and 1 written in Roman numerals is "I" .

So if we now subtract the "I" from "XIX", then we get :

$XIX-I=XX$

Now we know that "XX" in Roman numeral denotes 20.

Therefore the above equation holds true.Roman numerals are indeed a numeral system that originated in ancient Rome but instead remained the standard way of writing numbers in Europe until the late Middle Ages.

Numbers are written using letter combinations from the Latin alphabet, each with a fixed integer value are roman numerals.
