The teacher will be very surprised to see your correct solution 😉

⌨

- As possible, simplify the expression with abstract sets
- Get result when you specific sets
- Find universal set, if the one is not defined
- Detailed solution with right order of operations

- Using negative
not(not(A) \ not(B ∪ C)) \ not(A) ∩ not(B) ∩ C ∪ A ∩ B ∩ C

- With union of sets
(B ∆ (A ∩ B)) ∩ (A ∪ B)

- With intersection of sets
((A ∪ B) ∆ C) ∪ (B ∩ C) ∪ (A ∩ C)

- With symmetric difference
A ∆ (B ∆ A)

- With universal set
(U \ C) \ (U \ B)

- With complement of sets
(A ∆ B ∆ C) \ D

Here defined symbols, which you should use when enter a expression with sets

- not(A) или U \ A
- – Universal set, without set A
- A ∪ B
- – union of sets A and B
- A ∩ B
- – intersection of sets A and B
- A ∆ B
- – symmetric difference of A and B
- A \ B
- – Complement of sets A and B
- U
- – Universal set
