Answer:
∼ : This symbol denotes similarity
∪ : This symbol means union
∩ : This symbol means Intersection
∅ : means an empty set
≠ : this symbol mean not equal to
! : This symbol means factorial
Step-by-step explanation:
Given symbols in the question:
∼ : This symbol denotes similarity
i.e the resemblance or likeness.
∪ : This symbol means union
i.e
A∪B element that belong to set A or set B
∩ : This symbol means Intersection
i.e
A∩B = Element that belong to set A and set B
∅ : means an empty set
For example
if A = { 1, 2, 3 } B = { 4, 5, 6 }
Then,
A∩B = ∅
≠ : this symbol mean not equal to
i.e
LHS is not equal to RHS
! : This symbol means factorial
i.e
If we write 3!
we solve it as 3! = 3 × 2 × 1
