intersection is where the intervals overlap

union is evetrything in either one

(-1,1) extends from -1 to 1

[0,6] extends from 0 to 6

If you supermimpose the two shaded intervals, you will see that the combined shaded interval is

(-1,6]

The stuff in [0,1) is shaded twice, but that's ok. It's part of everything that's shaded.
