The expression in the image is a Boolean algebra expression:

$A \cdot \overline{B} + A \cdot B + \overline{A} \cdot B$

Let's simplify it step by step.

Step 1: Factor common terms

We can group terms to look for simplifications: $A \cdot (\overline{B} + B) + \overline{A} \cdot B$

Step 2: Apply Boolean identity

Using the Boolean identity $\overline{B} + B = 1$, the expression simplifies to: $A \cdot 1 + \overline{A} \cdot B$

This simplifies further to: $A + \overline{A} \cdot B$

Step 3: Apply the Distributive Law

The next step uses the Distributive Law: $A + \overline{A} \cdot B = (A + \overline{A}) \cdot (A + B)$

Using the identity $A + \overline{A} = 1$: $1 \cdot (A + B) = A + B$

Final Simplified Expression:

$A + B$

The given Boolean expression simplifies to $A + B$.
