Hello, I have been trying to do my math homework for a few hours now and can not figure out how to find the indicated intersection or union in interval notation.
Example: (1,5)n[0,8)
Please help me!!

Draw two number lines, one under the other
(1,5) extends from 1 to 5
underneath,
[0,8) extends from 0 to 8
The intersection is just where the intervals overlap: [0,5)

Thank You Steve. Now I understand the intersection. Could you please explain the union now.
Ecample: (1,1)U[0,6]
