What does a ∩ B mean?
the intersection of setsA∩B is a set that consists of elements that are common in both A and B. The formula A intersection B represents the elements that are present both in A and B and is denoted by A∩B. So, using the definition of the intersection of sets, A intersection B formula is: A∩B = {x : x ∈ A and x ∈ B}
What does a UB means?

What does a ∩ B mean in Venn diagrams?
intersectionThe intersection symbol ∩ The area where two sets intersect is where objects share both categories. In our example diagram, the teal area (where green and purple overlap) represents the intersection of A and B, which we notate as A ∩ B.Feb 10, 2022
What is a ∪ B ∩ C?
∪ means union: A∪B is set of elements in either set A or set B. ∩ means intersection: B∩C is set of elements in both set B and set C. A∪(B∩C)⊆(A∩B)∪(A∩C) If you have an element either from set A or from both sets B and C, then you have elements which are from both either sets A or B and from either sets A or C.Aug 23, 2016
What does a U B mean in math?
The union of two sets A and B is a set that contains all the elements of A and B and is denoted by A U B (which can be read as "A or B" (or) "A union B").
What does a UB mean in math sets?
1 Expert Answer (A' ∪ B') means all not in A but in U, AND all not in B but in U. That's {2, 5, 6} ∪ {3, 6, 7, 8} or {2, 5, 6, 7, 8}. Now, (A ∪ B)' means whatever is NOT in both A and B (but is still in U. That's {3, 5, 6, 7, 8}. The intersection of the two sets found above is next.Mar 29, 2016
How do you find AB in a set?
To find the difference A - B of these two sets, we begin by writing all of the elements of A, and then take away every element of A that is also an element of B. Since A shares the elements 3, 4 and 5 with B, this gives us the set difference A - B = {1, 2}.Jun 13, 2018
What does the M stand for in math?
In algebra, the letter "m" refers to the slope of a line. The slope of a line determines both its steepness and direction.
What does AB mean in sets?
A-B is the set of all elements that are in A but NOT in B, and B-A is the set of all elements that are in B but NOT in A. Notice that A-B is always a subset of A and B-A is always a subset of B.
What does U mean in math?
the union of two setsIn math, the symbol U represents the union of two sets. The union is the set of all elements included in either (or both) sets.Nov 8, 2021
What is a ∪ B C?
In symbols: This idea subsumes the preceding sections—for example, A ∪ B ∪ C is the union of the collection {A, B, C}. Also, if M is the empty collection, then the union of M is the empty set.
What does a Nb mean in math?
N.B. (Nota Bene) means “note well” or “pay attention to the following”. (It is used to imply that the wise reader will pay especially careful attention to the what follows and is never followed by a comma.)Jan 21, 2007
