What are the potential pitfalls of using math operators in PHP with non-natural numbers?

When using math operators in PHP with non-natural numbers, potential pitfalls include unexpected results due to floating-point precision errors and division by zero errors. To solve these issues, you can use functions like round(), floor(), ceil(), and number_format() to handle floating-point precision errors, and check for division by zero before performing any division operations. 

// Example of handling floating-point precision errors
$num1 = 0.1;
$num2 = 0.2;
$sum = round($num1 + $num2, 2);
echo $sum; // Output: 0.3

// Example of checking for division by zero
$numerator = 10;
$denominator = 0;
if ($denominator != 0) {
    $result = $numerator / $denominator;
    echo $result;
} else {
    echo "Division by zero error!";
}
