How can PHP developers improve their code readability when dealing with complex number manipulation tasks?

Complex number manipulation tasks can become difficult to read and understand if not properly organized. PHP developers can improve code readability by breaking down complex operations into smaller, more manageable steps, using descriptive variable names, and adding comments to explain the logic behind the calculations.

// Example of improving code readability for complex number manipulation tasks
$real1 = 5;
$imaginary1 = 3;
$real2 = 2;
$imaginary2 = 4;

// Calculate the sum of two complex numbers
$sum_real = $real1 + $real2;
$sum_imaginary = $imaginary1 + $imaginary2;

echo "Sum: " . $sum_real . " + " . $sum_imaginary . "i";
