## What is value of A and B?

The value of a+b is a+b. In other words, add a to b. Of course, it would be more meaningful if there were VALUES given to a and b, like a= 3 and b = 4. Then a + b would equal 7.

## What is the meaning of a ∆ B?

A △ B is the set of all those elements which belongs either to A or to B but not to both. A △ B is also expressed by (A ∪ B) – (B ∩ A). It follows that A △ ∅ = A for all subset A, A △ A = ∅ for all subset A.

**What is the formula for a ∆ B?**

A ∆ B = (A U B) – (A ∩ B) It implies that A ∆ B represents a set that contains the elements from the union of two sets, A and B, minus the intersection between them.

### What is A and B in algebra?

A and B in algebra stand for any variables of real numbers.

### What is a ∩ B?

A intersection B is a set that contains elements that are common in both sets A and B. The symbol used to denote the intersection of sets A and B is ∩, it is written as A∩B and read as ‘A intersection B’. The intersection of two or more sets is the set of elements that are common to every set.

**How do I find my PA and B?**

Formula for the probability of A and B (independent events): p(A and B) = p(A) * p(B). If the probability of one event doesn’t affect the other, you have an independent event. All you do is multiply the probability of one by the probability of another.

## What is Algebra 1A and 1B?

Description: Algebra 1A/1B is a two year course which will cover all topics in a traditional one year Algebra 1 course. Description: Algebra 1A/1B is a two year course which will cover all topics in a traditional one year Algebra 1 course. The slower pace will allow time for intervention as needed.

## What property is a/b c?

Algebra Properties and Definitions
