What are the formulas of sets Class 11?
Sets Formulas of Difference of Sets
- A – A = Ø
- B – A = B⋂ A’
- B – A = B – (A⋂B)
- (A – B) = A if A⋂B = Ø
- (A – B) ⋂ C = (A⋂ C) – (B⋂C)
- A ΔB = (A-B) U (B- A)
- n(AUB) = n(A – B) + n(B – A) + n(A⋂B)
- n(A – B) = n(A∪B) – n(B)

What is set math class 11?
Before learning sets for class 11, let us know first what is a set. A set is a well-defined collection of objects, whose elements are fixed and cannot vary. It means set doesn’t change from person to person. Like for example, the set of natural numbers up to 7 will remain the same as {1,2,3,4,5,6,7}.
