What is a complement of a set and example?
What Is the 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}.
What is the complement in math?
The complement of a set in math is defined as a set of elements in the universal set that is not part of the original set. Explore the definition of the subset and complement of the subset of a universal set, how to determine the complement of a subset and the correct notation for writing a subset and its complement.
What is the symbol of complement of a set?

Mathematics Set Theory Symbols
| Symbol | Symbol Name | Meaning |
|---|---|---|
| Ac | complement | all the objects that do not belong to set A |
| A ∆ B | symmetric difference | objects that belong to A or B but not to their intersection |
| a∈B | element of | set membership |
| (a,b) | ordered pair | collection of 2 elements |
Which of the following is complement of set A?
For any set A which is a subset of the universal set U , the complement of the set A consists of those elements which are the members or elements of the universal set U but not of the set A . The complement of any set A is denoted by A′ .
What is the complement of set B?
If the set A is the suit of spades, then the complement of A is the union of the suits of clubs, diamonds, and hearts. If the set B is the union of the suits of clubs and diamonds, then the complement of B is the union of the suits of hearts and spades.
How do you find AUB )’?
You find AUB by looking at set A and set B and discarding one of each item that appears in both sets. Lump them all together, and that’s the union.
What is the complement of a union B?
A complement union B complement can be understood as the union of the complements of each of the two sets. The union of the complement of set A and set B is equal to the difference of the universal set(μ) and the intersection of the two sets (A n B).
What is the complement of 4?
Decimal example

Is a B the same as AB in sets?
The difference of sets, say A and B, is also written as A/B ( Remove the elements in A that are common with B).
What is a low complement level?
what low levels mean: low complement levels in lupus usually mean increased disease activity. When the body uses the complement system to clear immune complexes from the blood it results in low complement levels. The complement proteins are not produced as quickly as they are being used.
What does ‘complement’ mean in set theory?
In set theory, the complement of a set A refers to elements not in A. When all sets under consideration are considered to be subsets of a given set U, the absolute complement of A is the set of elements in U but not in A.
What is a complement and a supplement?
As nouns the difference between supplement and complement is that supplement is something added, especially to make up for a deficiency while complement is . is that supplement is to provide or make a supplement to something while complement is to complete, to bring to perfection, to make whole.
What is the complement of an intersection?
The intersection of two sets contains only the elements that are in both sets. The intersection is notated A ⋂ B. More formally, x ∊ A ⋂ B if x ∊ A and x ∊ B. The complement of a set A contains everything that is not in the set A. The complement is notated A’, or Ac, or sometimes ~A.
