The world is full of wonders, and there are many interesting things in our mathematics kingdom. Interesting chicken and rabbit in the same cage, strange mathematical black hole, in which I found some wonderful mathematical laws. I remember once when I was doing an Olympic math problem, I met an equation problem 18X=20. When I divide 20 by 18, I find that the number is1.11... which is a pure cyclic decimal. Later, I wrote the score of 10/9. When I finished writing the answer and looked at the answer to this question, I guessed: when the dividend is an integer ten, if you subtract the tenth number from this number and then divide the original number by the reduced number, this number is1.11... or a tenth of a fraction.

Thinking of this, I hesitate: is this guess accurate? Can it be wrong? With this question in mind, I began to look it up with other numbers: the tenth place of 30 minus 3 equals 27, and then 30 is divided by 27. What I found at this moment was really1.11... and 10/9. Later, I used 70 and 60 respectively to prove whether my statement was correct. If my idea is correct, I will prove it with facts.

After that, I continued to use this rule to check the whole hundred digits, and found that the number was 1.0 10 1 ... or one hundred out of ninety. According to this rule, we can get that the integer digits are 1.0005438+0. ...

In this wonderful mathematical kingdom, as long as we keep exploring and discovering, we can find many interesting and unfamiliar mathematical problems. The method of conjecture verification is an important way for human beings to explore the unknown. Many scientific laws are discovered by guessing, and then constantly verified, guessed and verified. Conjecture verification is also an important mathematical thinking method. When listening to the teacher, we should pay attention to learning this way of thinking from the teacher, and at the same time, we should try our best to explore ourselves in our ordinary life.
