As we all know, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 is the most basic symbol in mathematics. Only with them can we carry out mathematical operations. And "0" is indispensable. With "0", we are much more convenient in counting and reading. However, you may not know that when the number "0" was first introduced into Europe, there was a very irritating story!

About 1500 years ago, European mathematicians did not know how to represent numbers with 0. They were still using Roman numerals at that time. Roman numerals are several symbols representing numbers, which are combined to represent different numbers according to certain rules. In this digital symbol, there is no 0 at all.

At that time, a mathematician of the Roman Empire discovered the symbol 0 from Indian notation. He found that with 0, it was much more convenient for people to do mathematical operations, so he introduced the way Indians used 0.

After a while, it was known by the Pope. At that time, Europe was in the dark Middle Ages, and the power of the church was very strong, and the power of the pope far exceeded that of the emperor. The Pope was very angry. He rebuked the scholar and said that the sacred number was created by God, and there was no "0" monster in the number created by God. Now anyone who wants to introduce it is blasphemy!

So the Pope ordered the mathematician to be arrested and tortured, and his 10 finger was broken with an iron clip, so that his hands were disabled and he could no longer hold a pen and write. In this way, the number 0 was actually banned by the ignorant and cruel Pope.

Although 0 is forbidden, brave Roman mathematicians still use the number 0 secretly in mathematical research, which makes it make a lot of contributions in mathematical research. Later, the number 0 was finally widely used in Europe, but the Roman numerals were swept into the historical garbage.
