Explanation:

Analyze the given equation

$$ a + bi + c + di = a + c + bi + di $$

Identify the change in order

$$
LATEXBLOCK0
$$

The terms \(bi\) and \(c\) have swapped positions.

Determine the algebraic property

$$ x + y = y + x \implies \text{commutative property} $$

Answer:

• identity property
• associative property
• commutative property (Correct answer)
• inverse property
