How can the order of operations (Punkt- vor Strichrechnung) be maintained when performing mathematical calculations in PHP?

When performing mathematical calculations in PHP, the order of operations can be maintained by using parentheses to group operations that should be performed together before others. This ensures that calculations are carried out according to the rules of arithmetic, such as performing multiplication and division before addition and subtraction.

// Example of maintaining order of operations in PHP
$result = (5 + 3) * 2; // Result will be 16 (5 + 3 = 8, 8 * 2 = 16)
echo $result;
