How can PHP developers ensure accurate results when working with negative numbers in their scripts?

When working with negative numbers in PHP scripts, developers should ensure that they are using appropriate functions and operators to handle these values correctly. One common mistake is forgetting to properly handle negative numbers in mathematical operations, which can result in inaccurate results. To ensure accurate results, developers should always use the correct operators and functions designed for working with negative numbers. 

// Example code snippet to ensure accurate results when working with negative numbers

// Multiplication
$resultMultiplication = $negativeNumber * $positiveNumber; // Correct way to multiply negative and positive numbers
