Interpreting descriptions of sets?

3 min read

Asked by: Tim Abro

How do you write a description of a set?

So the description of this one would be the days of the week. So when it asks you to describe you literally are just writing out what does it contain. The second one that I have is a set of numbers.

What is interpret of set?

(It is a set included between the outside brackets.) Another example that shows how sets are interpreted includes the following: If B is the set of real numbers that are solutions of the equation x2 = 9, then the set can be written as B = {x: x2 = 9}, or B is the set of all x such that x2 = 9. Thus B is {3, -3}.

How do you interpret the relations on sets?

A relation between two sets is a collection of ordered pairs containing one object from each set. If the object x is from the first set and the object y is from the second set, then the objects are said to be related if the ordered pair (x,y) is in the relation. A function is a type of relation.

How do you describe sets in math?

A set in mathematics is a collection of well defined and distinct objects, considered as an object in its own right. Sets are one of the most fundamental concepts in mathematics.

What are the 3 ways to describe a set?

There are three main ways to identify a set:

  • A written description,
  • List or Roster method,
  • Set builder Notation,


What is descriptive form of set example?

Descriptive Form: State in words the elements of the set. Example: A= Set of first five natural numbers.

What are the types of set?

Types of a Set

  • Finite Set. A set which contains a definite number of elements is called a finite set. …
  • Infinite Set. A set which contains infinite number of elements is called an infinite set. …
  • Subset. …
  • Proper Subset. …
  • Universal Set. …
  • Empty Set or Null Set. …
  • Singleton Set or Unit Set. …
  • Equal Set.

What are the symbols for sets?

Mathematics Set Theory Symbols

Symbol Symbol Name Meaning
A ∩ B intersection Elements that belong to both the sets, A and B
A ⊆ B subset subset has few or all elements equal to the set
A ⊄ B not subset left set is not a subset of right set
A ⊂ B proper subset / strict subset subset has fewer elements than the set

How do you write a complement of a set?

The complement of set A is defined as a set that contains the elements present in the universal set but not in set A. For example, Set U = {2,4,6,8,10,12} and set A = {4,6,8}, then the complement of set A, A′ = {2,10,12}.

How do you describe a subset and universal set?

The universal set is defined as a set containing all elements or members of all the related sets, known as its subsets, whereas the union of sets is one of the set operations between two sets where the resultant set contains all the elements which are common elements of both the initial sets.

What are the differences and complements of sets?

Complement and Difference of Sets



The complement of a set A is denoted by A’ or Ac and it is the difference of the sets U and A, where U is the universal set. i.e., A’ (or) Ac = U – A. This refers to the set of all elements that are in the universal set that are not elements of set A.

What do you mean by sets explain with its types?

Set is defined as a well-defined collection of objects. These objects are referred to as elements of the set. Different types of sets are classified according to the number of elements they have. Basically, sets are the collection of distinct elements of the same type.

What are the 4 types of sets?

Answer: There are various kinds of sets like – finite and infinite sets, equal and equivalent sets, a null set. Further, there are a subset and proper subset, power set, universal set in addition to the disjoint sets with the help of examples.
