Math trivia, trivia about math

1, zero. In the early days, it was thought that "1" was the beginning of the "numeric character list", and it led to other numbers such as 2, 3, 4, 5, etc. The purpose of these numbers is to count those objects that are real, such as apples, bananas, pears, etc.

It wasn't until later that I learned how to count the number of apples in a box when there were no apples left.

2. Digital system.

The number system is a way to deal with "how much". Different cultures have adopted a variety of different methods in different eras, extending from the basic "1, 2, 3, a lot" to the highly complex decimal representation used today.

is the most well-known number in mathematics. Forgetting all the other constants in nature does not forget it either, always appearing first in the list. If the number also has an Oscar, then it will surely win every year.

Or pi, which is the ratio of the circumference of the circumference of the circle to its diameter. Its value, i.e., the ratio between these two lengths, does not depend on the size of the circumference. Regardless of whether the circumference is large or small, the value is constant.

It arises from the circumference, but in mathematics it is ubiquitous, even in places that have nothing to do with the circumference.

4. Algebra. Algebra gives a new way of solving interdisciplinary problems, a "roundabout" method of dating. This "maneuver" is "reverse thinking".

Let's consider this question, when adding 17 to the number 25, the result will be 42. This is positive thinking. These numbers, all you need to do is add them up.

But suppose you already know the answer to 42 and ask a different question, i.e., what number you want to know now and add 25 to get 42. This is where reverse thinking comes in. To know the value of the unknown x, it satisfies the equation 25 x 42, and then simply subtract 25 from 42 to know the answer.

5. Functions. Leonhard Euler was a Swiss mathematician and physicist. Euler was the first to use the word "function" to describe expressions that contain various parameters, for example: y = f(x), and he was one of the pioneers of applying calculus to physics.

The content of the math trivia is as follows:1. The first to use the small dot as a decimal point was a German mathematician named Kravis.

2. China is the first country to use rounding for calculation.

3. The missing number system is a way to deal with "how much". Different cultures have adopted a variety of different approaches in different eras, extending from the basic "1, 2, 3, many" to the highly complex decimal representation of the square attack that we use today.

4. is the most famous number in mathematics. Forget all the pats in nature, and the other constants will not forget it, always appearing in the first position on the list. If the number also has an Oscar, then it will surely win every year.

5. e is an approximate number, which is an irrational number, so we cannot know its exact value.
