Question

When a set is subtracted from itself then what is the result​

Answer 1

Answer :

• Set is a well defined group of objects.
• It is written in flower brackets - { }
• Subtraction of set A and B i.e, A - B is equal to the set of elements in A and not in B
• A - B = {x:x $\in$A $\notin$B}
• So, A - A will be a null set.

When a set is subtracted from itself, the result will be a null set.
