The number "0" looks monotonous, but it doesn't exist. In fact, it is very rich and hides a lot. Zero is special in mathematics. No matter what you do, you should consider zero. "0" is often used as a symbol in geometry. The uniqueness of "0" comes from some concepts or problems. For example, every rational number has a reciprocal, while "0" does not. Rational numbers are divided into positive numbers and negative numbers. "0", a number is divided into one category, isn't this special? In divisor, only zero cannot be divided. Zero is the dividend. No matter what number you divide (except "0"), you will get zero.

Math Games Four students are playing math games together. Xiaohua, Xiaojun and Xiaoming put their hands behind their backs. The tiger showed them two white balls and three red balls, then stuffed a red ball into their hands from behind, and the remaining two white balls hid quietly. Then, each of them is allowed to see what color ball the other two are holding, but they are not allowed to see the ball in their own hands. When Tiger saw it, he asked them to quickly judge what color ball they were holding. Xiao Ming was the first to guess the color of the ball in his hand. How did he judge?
Xiao Ming thought: Obana is a red ball, so my ball may be a white ball or a red ball. If I take a white ball, Mr. Obana will soon think that what they are holding is definitely not a white ball. Because at this time, Xiaohua can guess that Xiaoming is holding a white ball in his hand. If I also hold a white ball, Xiaojun will immediately say that he is a red ball because there are only two white balls. Xiaojun can also say that he is a red ball at once, because there are only two white balls. Xiaojun can also make the above speculations and make quick judgments. Now both of them are hesitating, so I must have a red ball in my hand.
The above are some related materials of mathematical manuscripts, hoping to help everyone.
