To solve the expression $4 + \frac{4}{4} \times 4$, we follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right)).

1. First, divide $4 \div 4 = 1$.
2. Then multiply $1 \times 4 = 4$.
3. Finally, add $4 + 4 = 8$.

Thus, the result of the expression is:

$\boxed{8}$

Here are five related questions to deepen your understanding:

1. What would the result be if you replaced the addition with subtraction?
2. How does the order of operations affect this calculation?
3. Can you try a similar expression but with parentheses to change the order of operations?
4. How would this expression change if you squared each term?
5. What happens if we divide the result by 2 at the end?

Tip: Always apply the order of operations carefully, especially when dealing with mixed arithmetic operations.
