Are there any best practices or recommended resources for learning PHP functions and their applications in mathematical calculations?

When learning PHP functions for mathematical calculations, it is recommended to start by understanding the basic arithmetic operators (+, -, *, /) and built-in math functions provided by PHP (e.g., abs(), sqrt(), pow()). Additionally, exploring online tutorials, documentation, and practice exercises can help in mastering PHP functions for mathematical calculations. 

// Example of using PHP functions for mathematical calculations
$num1 = 10;
$num2 = 5;

// Addition
$sum = $num1 + $num2;
echo "Sum: " . $sum . "<br>";

// Subtraction
$diff = $num1 - $num2;
echo "Difference: " . $diff . "<br>";

// Multiplication
$product = $num1 * $num2;
echo "Product: " . $product . "<br>";

// Division
$quotient = $num1 / $num2;
echo "Quotient: " . $quotient . "<br>";

// Square root
$sqrtNum1 = sqrt($num1);
echo "Square root of num1: " . $sqrtNum1 . "<br>";

// Power
$powerNum1 = pow($num1, 2);
echo "num1 raised to the power of 2: " . $powerNum1 . "<br>";
