How to use arithmetic operators in PHP

Answer 1

$x = 10;
$y = 30;

echo $x + $y . "<br />"; //  40  // Sum
echo $x - $y . "<br />"; // -20  // Subtraction
echo $x * $y . "<br />"; // 300  // Multiplication
echo $x / $y . "<br />"; // 0.33333333333333  // Division

$x = 12;
$y = 10;
echo $x % $y . "<br />"; // 2 //Modulus - the remainder of $x divided by $y     

$x = 2;
$y = 3;
echo $x ** $y . "<br />"; // 8 // Exponentiation // From PHP 5.6
