The upside down U in math, i. Union and intersection concepts are heavily used in solving problems related to Sets and Venn diagrams. In this topic, we will study the upside down U in math, its significance, and the difference between simple U and upside down U along with numerical examples and applications. The upside-down U in math is commonly known as an intersection between two or more sets, which is the collection of common elements of all the sets.

The following list of mathematical symbols by subject features a selection of the most common symbols used in modern mathematical notation within formulas , grouped by mathematical topic. As it is impossible to know if a complete list existing today of all symbols used in history is a representation of all ever used in history, as this would necessitate knowing if extant records are of all usages, only those symbols which occur often in mathematics or mathematics education are included. The following list is largely limited to non-alphanumeric characters. It is divided by areas of mathematics and grouped within sub-regions. Some symbols have a different meaning depending on the context and appear accordingly several times in the list. Further information on the symbols and their meaning can also be found in the respective linked articles. Note: the power function is not represented by its own icon, but by the positioning of the exponent as a superscript. Contents move to sidebar hide. Article Talk.

Different properties of upside-down U or intersection, frequently used in solving set problems, are given below. But what would happen if one of the sets contains nothing? Idempotent Property: According to this property, if we take the intersection of Set X with itself, the result will be A itself, and we can write it as:. Example A husband and wife work in the same company. It is the name of an Egyptian harp, which was of that shape. The upside-down U in math is commonly known as an intersection between two or more sets, which is the collection of common elements of all the sets. Let us see some numerical examples of the upside-down U symbol in math statistics and probability. Suppose we take two sets, A and B, then the intersection between these two sets is represented by the Venn diagram drawn below:. Different properties of upside-down U or intersection, frequently used in solving set problems, are given below. The distributive property for three sets, X, Y and Z, can be written as.
