  • “ A minus B” Or "A – B"

notes

The difference of the sets A and B in this order is the set of elements which belong to A but  not to B. Symbolically, we write A – B and read as “ A minus B”.

Example-  Let A = { 1, 2, 3, 4, 5, 6}, B = { 2, 4, 6, 8 }. Find A – B and B – A.
Solution-  A – B = { 1, 3, 5 } and  B – A = { 8 }
We note that A – B ≠ B – A.
