What does a comma mean in math?

The comma is used in mathematics to divide long numbers into smaller units, aiding in the identification of place value. In a number that is separated into short segments, the comma is a numeric symbol rather than a mark of punctuation. Consequently, there should be no space before or after the mathematical comma.

How do you read AB in math?

“a/b” without specific context “should” be mathematical, not really English. In English, mathematical “a/b” becomes ” A over B”, meaning “A divided by B.” What’s the context, please?

What is a B in math example?

A – B means elements of A which are not the elements of B. Solved examples to find the difference of two sets: 1. A = {1, 2, 3} and B = {4, 5, 6}.

What is b math term?

Base. In geometry, the base of a shape is the side (usually the bottom) that forms a right (90 degree) angle with the height of the object.

What does a B mean discrete math?

CS 441 Discrete mathematics for CS. Set difference. Definition: Let A and B be sets. The difference of A and B, denoted by A -B, is the set containing those elements that are in A but not in B. The difference of A and B is also called the complement of B with respect to A.

What does U mean in precalculus?

more … The set made by combining the elements of two sets. So the union of sets A and B is the set of elements in A, or B, or both. The symbol is a special “U” like this: ∪

How do you find the set AB?

An Example

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}.

What set difference?

Set difference is a generalization of the idea of the complement of a set and as such is sometimes called the relative complement of T with respect to S. The symmetric difference between two sets S and T is the union of S – T and T – S.

What does the U and upside down U mean?

These are used in set notation. U stands for union. And upside down U stands for intersection.. .For example given the set A = {1, 2, 3} and B = {3, 4, 5} Then A U B = {1, 2, 3, 4, 5} and A intersection B = { 3 }

What is upside down U?

The circles A and B represent sets. “Intersect” is represented by an upside down U. The intersection is where the circles overlap. “Union” is represented by a right-side up U.

What is P A intersection B?

P(A∩B) is the probability of both independent events “A” and “B” happening together, P(A∩B) formula can be written as P(A∩B) = P(A) × P(B), … P(A∩B) = Probability of both independent events “A” and “B” happening together. P(A) = Probability of an event “A” P(B) = Probability of an event “B”
