It looks like you've provided the expression $(A + b)$, which is a simple algebraic expression with two terms, $A$ and $b$, enclosed in parentheses.

• If you want to expand or further manipulate this expression, please clarify whether you need additional operations or have any specific conditions for $A$ and $b$.
• Otherwise, without more context, this expression remains as it is.

Would you like to explore further? Feel free to share additional details or ask questions!

Here are five related questions:

1. Do you need to expand or simplify an expression involving $(A + b)$?
2. Are $A$ and $b$ variables, constants, or matrices?
3. Would you like to solve for $A$ or $b$ given an equation?
4. Is this part of a larger problem or equation?
5. Do you need help with factoring or combining terms in expressions like $(A + b)$?

Tip: When working with expressions, always check for opportunities to simplify or combine like terms before performing further operations.
