Question

(-1;4) U, intersectat, \ [0;5]
[-∞;0) U, intersectat, \ [-3;2]

Answer 1

(-1,  4) ∩ [0,  5] = [0,  4)

[-∞, 0) ∩  [-3, 2] = [-3, 0)

Answer 2

(-1; 4) U [0,5]= (-1 ;5]

(-1; 4) n [0;5]= [0,4)

(-1; 4) - [0,5]=(-1;0)

[0,5]- (-1,4)=[4,5]

[-∞;0) U [-3;2] =[-∞,2]

[-∞;0) n [-3;2] = [-3,0)

[-∞;0)  \ [-3;2] = [-∞, -3)

[-3;2] \ [-∞;0) =[0,2]
