# Thread: AUO not... everything A and O are not not??

1. ## AUO not... everything A and O are not not??

I m confused by a problem: A not, universal set not, O not. its AUO with a line over all three. How does that read if I have to put the problem into words?
Basically its giving me three sets of names, A J and O, then asking me to pick which names to list based on the problem AUO 'not'. I am reading that as "list everything A and O are not not??

2. If I am interpreting correctly, the $\overline{A\cup O}$ means not in A or O. The complement of A or O.

I honestly cannot understand what you have written.
Is it something like this: $\overline{A \cup B}=\overline{A}\cap \overline{B}$?
You can use LaTeX code.
$$\overline{A \cup B}=\overline{A}\cap \overline{B}$$
