Answer 1

x reunit y = 1,2,3,4,5,6,7,8
x intersectat y = 3,4,5
x/y= 1,2
y/x= 6,7,8

Answer 2

x={1,2,3,4,5}
Y={3,4,5,6,7,8}

x∪Y={1,2,3,4,5,6,7,8,} - reunit (impreuna toate elementele celor 2 multimi, fara insa a le repeta pe cele comune)

x∩Y={3,4,5} intersectia (elementele pe care le regasesti in ambele multimi

x/Y={1,3}  ce are multimea X si nu are multimea Y

Y/Y={6,7,8}  ce are multimea Y si nu are multimea X
