# 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
* 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.
```<?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
2
0
-1
-1
```
