In what situations can overcomplicating simple calculations, like percentage discounts, lead to errors in PHP programming?

Overcomplicating simple calculations, such as percentage discounts, can lead to errors in PHP programming by introducing unnecessary complexity that increases the likelihood of mistakes in the code. To avoid this, it's best to keep calculations as straightforward as possible by breaking them down into smaller, more manageable steps. 

// Example of calculating a percentage discount without overcomplicating the code
$originalPrice = 100;
$discountPercentage = 20;

// Calculate the discount amount
$discountAmount = $originalPrice * ($discountPercentage / 100);

// Calculate the final price after applying the discount
$finalPrice = $originalPrice - $discountAmount;

echo "Original Price: $" . $originalPrice . "\n";
echo "Discount Percentage: " . $discountPercentage . "%\n";
echo "Discount Amount: $" . $discountAmount . "\n";
echo "Final Price: $" . $finalPrice;
