Union Math Symbol

The unicode standard encodes almost all standard characters used in mathematics.

Union math symbol. A is a subset of b. Symbol symbol name meaning definition example set. A b 3 7 9 14 28 a b. In set theory the union denoted by of a collection of sets is the set of all elements in the collection.

For many of the symbols below the symbol is usually synonymous with its corresponding concept but in some situations a different convention may be used. Mathematical operators and symbols are in multiple unicode blocks some of these blocks are dedicated to or primarily contain mathematical characters while others. It is commonly used in mathematics and engineering. A 3 7 9 14 b 9 14 28 such that.

The diagram below illustrates set union. Given two sets a and b the union of a and b written a b is the set c of all elements that are in a or in b. Unicode technical report 25 provides comprehensive information about the character repertoire their properties and guidelines for implementation. A collection of elements.

One is obtained from the other by a vertical. The union symbol denotes the union of two set s. A mathematical concept is independent of the symbol chosen to represent it. For explanation of the symbols used in this article refer to the table of mathematical symbols.

The symbol used for the union of the two sets a and b is given by a b. Objects that belong to set a and set b. One way to remember the symbol refers to union is to notice its resemblance to a capital u which is short for the word union be careful because the symbol for union is very similar to the symbol for intersection. The following is a list of mathematical symbols used in all branches of mathematics to express a formula or to represent a constant.

Objects that belong to set a or set b.
