We can prove that
When A and B are two sets(A≠B)
(A-B) = (A∩B') = (A-(A∩B))
{We can also confirm them using venn diagram}
From first and third relation
A-B = A - (A∩B)
By cancelling A from both side
I get B = (A∩B)
Which is only possible when A and B are same set.
What is wrong in my proof , is it not valid to cancell sets A from both side(if yes then why?)
