What are common issues faced by PHP beginners when trying to write scripts for mathematical operations like finding square roots?

Common issues faced by PHP beginners when trying to write scripts for mathematical operations like finding square roots include incorrect syntax, improper use of mathematical functions, and handling of invalid inputs (such as negative numbers). To solve these issues, beginners should ensure they are using the correct syntax for mathematical operations, properly call the sqrt() function to find square roots, and add validation to handle negative numbers if needed. 

<?php

// Example code snippet to find the square root of a number

$number = 16;

if($number >= 0){
    $squareRoot = sqrt($number);
    echo "The square root of $number is: $squareRoot";
} else {
    echo "Invalid input: Cannot find square root of a negative number.";
}

?>
