Question

What does AB represent in set like what does this expression mean
and what operation does A(BC) is

Answer 1

Step-by-step explanation:

A/B is the set of those elements which belongs to A but doesn't belongs to B

Mathematically , A/B ={ x : x € A and x does not € B}

Here, € “symbol is used for belong to”

OR you can say that A/B = A difference ( A intersection B )

Again , let me give you an example ao that the things will be clear to you

let,

A = {1,2,3,4,5,6,7,8,9,10}

B= {2,4,6,8,10}

then A/B = {1,3,5,7,9}
