Arithmetic Operators in PHP : Tutorial

Arithmetic operators are the nothing but simple addition, subtraction, multipication and division operators that we use in our day to day life for basic calculations

Arithmetic Operators

- Subtraction
+ Addition
* Multiplication
/ Division
% Modulus

Division operator (/) returns a float value unless the two operands are integers. Operands of Modulus (%) are converted to integers before they are processed. The result of Modulus Operator (%) has the same sign as the dividend.

Example : Addition (+)

<?php

$a = 2;
$b = 2;

$c = -12;
$b = 22;

echo $a + $b   ."<br>";
echo $c + $d   ."<br>";
}

?>

Output


4
10

Example : Subtraction (-)

<?php

$a = 2;
$b = 2;

$c = -8;
$d = 2;

echo $a - $b   ."<br>";
echo $c - $d   ."<br>";
}

?>

Output


0
-10

Example : Division (/)

<?php

$a = 2;
$b = 2;

$c = -4;
$d = 5;

echo $a / $b   ."<br>";
echo $c / $d   ."<br>";
}

?>

Output


1
-0.8

Example : Multiplication (*)

<?php

$a = 2;
$b = 2;

$c = -2;
$d = 2;

echo $a * $b   ."<br>";
echo $c * $d   ."<br>";
}

?>

Output


4
-4

Example : Modulus (%)

<?php

$a = 2;
$b = 4;

$c = 4;
$d = 2;

$e = -3;
$f = 2;

$g = -3;
$h = -2;

echo $a % $b  ."<br>";
echo $c % $d  ."<br>";
echo $e % $f  ."<br>";
echo $g % $h  ."<br>";
}

?>

Output
