| * | Multiplication | 10 * 3 | 30 |
| / | Division | 10 / 3 | 3.3333333333333 |
| % | Modulus (remainder) | 10 % 3 | 1 |
| ** | Exponentiation (power) | 10 ** 3 | 1000 |
<?php
$a = 10;
$b = 3;
echo ($a + $b) . "<br>";
echo ($a - $b) . "<br>";
echo ($a * $b) . "<br>";
echo ($a / $b) . "<br>";

Division always gives a float when the result is not a whole number. Use intdiv() if you need only the whole part. Read all operators in PHP Operators.
