0 is the smallest non-negative integer. Natural numbers may or may not include 0, but the fact that 0 is an integer. Even outside the framework of numbers, 0 was excluded from operations such as addition and multiplication.

The natural number next to 0 is 1, and 0 is not the next natural number. Natural numbers may or may not include 0, but this does not affect the fact that 0 is an integer. It was thought that 0, that is, without anything, was meaningless and therefore not a number.
0 is the smallest non-negative integer.
The concept of zero, which seems simple and intuitive today, has a rich and complex history spanning centuries and cultures. In the KBO league, No. 0 Gong Pil-seong and Kim Kang-min, and No. 0 Kim Gyeong-gi can be said to be representative examples. From the beginning, number was thought to have been created to 'count' the number of objects. However, when writing numbers, because the number of strokes is complicated, it is usually replaced with a simplified round shape, 〇.
But it doesn't say '0 apples'. Gong Pil-seong, a leading player with number 0 in the 1990s and 2000s, had no choice but to change his uniform number during his third year as a professional. Just as 1, 2, 3 are 一, 2, 3 in Chinese characters, 0 is ‘zero’ in Chinese characters. Adding (or subtracting) 0 to any number leaves that number unchanged;
In mathematical terminology, 0 is the additive identity.
So can factorial only be defined in 0 and positive integers? 0 (zero) is a number representing an empty quantity. The natural number next to 0 is 1, and 0 is not the next natural number. Euler, a Swiss mathematician in the 18th century, expanded the factorial to be defined in all numbers, like this.
Zero, represented by the number 0, is the basic structure of the number system. However, in other cases, 0 can be defined as a natural number. In this respect, compared to other numbers from 1 to 9, 0 is definitely.
