It seems that your input contains some symbols that are not fully formatted, making it difficult to interpret clearly. Based on what you've provided:

1. There is a display mode with A in one part of the expression.
2. The other part includes \overline{\text{B}} (indicating B with an overline) and the text "ouB."

Could you clarify the missing parts or your goal with this expression? If you're working on a specific math problem or need to discuss certain concepts, I can assist further with the details.

Do you need help with how to format this equation or some other mathematical concept?

Here are some related questions:

1. Are you working with sets or boolean logic (since you mention "ouB")?
2. What does A represent in this context?
3. Is the overline on B referring to a complement (in set theory or logic)?
4. Are you combining logic statements or discussing functions?
5. Would you like help formatting the entire equation?

Tip: Always double-check math notation for clarity, especially in expressions involving complements, sets, or logic.
