Ternary is a base 3 carry system.
It has been used in computers by researchers of Moscow University, and also involves the research field of photonic computers.
Symmetric ternary can represent all integers more conveniently than binary.
Ternary is a system of "three in one, one out of three".
Ternary numbers include "0, 1 and 2." Electrical signal (-1), 0, 1.
From right to left, the decimal places of ternary numbers are 1, 3,9,27,81,243. ...
After the decimal point of ternary numbers, from left to right, there are 3 decimal places, 9 decimal places, 27 decimal places and 8/kloc-0 decimal places. ...
When writing, put parentheses and add the subscript 3, such as (120 1)3. It can't be pronounced as 120 1, because they correspond to bits 27, 9, 3 and 1, not hundreds of bits!

2. What aspects and things are binary, ternary, octal, octal and octal used in mathematics?
Binary: 0 1
Widely used in digital and other things, such as computers, digital storage and so on.
Ternary: 0 12
Things commonly used in electronics, such as transistors and other things with three-pole characteristics.
Octal: 0 1234567
Generally, it is an extension of binary. If you set the color of every point in the computer with binary 0 1, you can't display more colors. So whenever octal display is displayed, that is, every point is set to octal, which is the so-called 8-bit (meta) color.
After that, hexadecimal and thirty-two are both.
Binary: 0 12345678
It is an extended application of ternary system.
3. A little knowledge about mathematics
1, zero
At a very early time, people thought that "1" was the beginning of "numerical character table", which further led to other numbers such as 2, 3, 4 and 5. The function of these figures is to count those physical objects, such as apples, bananas and pears. Only later, when there were no apples in the box, did I learn how to count the apples in the box.
2. Digital system
Digital system is a way to deal with "how much". Different cultures have adopted different methods in different times, from the basic "1, 2,3, many" to the highly complex decimal notation used today.
3,π
π is the most famous number in mathematics. Forget all other constants in nature, and you won't forget them. π always appears at the first place in the list. If the number also has an Oscar, then π will definitely win the prize every year.
π or π is the ratio of the circumference of a circle to its diameter. Its value, that is, the ratio of these two lengths, does not depend on the size of the circumference. Whether the circumference is large or small, the value of π is constant. π comes from the circumference, but it is everywhere in mathematics, even involving those places that have nothing to do with the circumference.
4. Algebra
Algebra gives a brand-new method of solving problems, a "cyclotron" method of playing with years. This kind of "maneuver" is "reverse thinking". Let's consider this problem. When the number 25 is added with 17, the result is 42. This is a positive idea. All you need to do is add up these figures.
However, if you already know the answer 42 and ask a different question, what you want to know now is what number and 25 add up to 42. You need to use reverse thinking here. To know the value of unknown x, satisfy equation 25+x=42, and then subtract 25 from 42 to know the answer.
5. Function
Leonhard euler is a Swiss mathematician and physicist. Euler was the first person to use the word "function" to describe expressions containing various parameters, such as: y? =? F(x), one of the pioneers who applied calculus to physics.
