A={0;1;3;4} ; B={1;2;4;5;6} C={2;4;7}

A ∩ B = {1,4 }

A/B = {0,3}

B/A = {2,5,6}

B ∩ C = {2,4}

B/C = {1,5,6}

A ∩C ={4}

B U C = {1,2,4,5,6,7}

(AUB) ∩ C = {0,1,2,3,4,5,6} ∩ { 2,4,7} = {2,4}

A = {0; 1; 3; 4}

B = {1; 2; 4; 5; 6}

C = {2; 4; 7}

A ∩ B = {1; 4}

A \ B = {0; 3}

B \ A = {2; 5; 6}

B ∩ C = {2; 4}

B \ C = {1; 5; 6}

A ∩ C = {4}

B ∪ C = {1; 2; 4; 5; 6; 7}

A ∪ B = {0; 1; 2; 3; 4; 5; 6}

(A ∪ B) ∩ C = {0; 1; 2; 3; 4; 5; 6} ∩ {2; 4; 7} = {2; 4}
