is the inclusion symbol: a contains b - then b is a subset of a or equal to a.
True contains: A is true to b - then a is a true subset of b.

Definitions
If any element of set A is an element of set B (any a a then a b), then set A is called a subset of set B, denoted as a b or b a, and is read as "set A contains set B" or set B contains Set A".
i.e.: a a has a b, then a b.
True subset: If set A is a subset of B, and A ≠ B, i.e., at least one element in B does not belong to A, then A is a true subset of B, which can be denoted as: A B.
Symbolic language: if a a, both have a b, and x b makes x a, then a b.

Anonymous users2024-02-13There are two commonly used symbols containing " in Chinese, which are " " " and " ".
It is generally used to indicate the relationship between the size of two quantities, for example, "a b" means that a is greater than b.
Indicates a subset symbol, which is generally used to indicate that one set is a subset of another set, such as "a b" indicates that a is a subset of b. In set theory, a subset is an important relationship that can be used to describe the inclusion relationship between sets.

True contains: A is true to be included in b - then a is a true subset of b, if b = then a = or or empty set. The inclusion of a relation is a relation in which the extension of one concept is contained in the extension of another concept. "Where s is p", then s and p have an inclusive relationship.
Truth is different from relation.
Symbolic concepts includedSet (abbreviated as set) is a basic concept in mathematics, it is the research object of set theory, until the 19th century The basic theory of set theory was created, and the samples in the set are called elements. If x is an element of the set a, it is denoted as x a. The elements in a collection have three characteristic determinities.
Heterogeneity. For example, if the set a=, then a cannot be equal to 1).
Out-of-order, such as a set and counting as the same set.

This means that element A belongs to a set, e.g., an element belongs to a set, such as 2.
A A means that A belongs to set A, and if A A, this A is an element of Set A.
m,1-m) can be seen as a set, its elements are all numbers between -m and 1-m, x -m, 1-m means x is in the range of this interval, i.e., -m

Weld symbols are generally composed of basic symbols and guide lines, and can also be supplemented with auxiliary symbols, supplementary symbols and weld dimension symbols if necessary. The form of the weld and the size of the groove are generally represented by the method of technical drawing on the drawing. In order to simplify the representation method of weld on the drawing, the expression method of weld symbol and groove size specified in the national standard is now adopted. >>>More
It means and, and the English symbol is equivalent to the word and. The earliest history of the character & dates back to the 1st century AD and is a ligature. The earliest & was much like a combination of e and t, but with the development of printing technology, this symbol gradually formed its own style and detached itself from its original shadow.
