Math operation in PHP

So,for this lesson,i will show u the operation in PHP.this will take a sec to understand this,trust me!
here is the code:

<html>
<head>
<title>Operation in PHP script</title>
</head>
<body>

<?php

$number1 = 13;
$number2 = 27;
$total = $number1 + $number2;

$connect_text = 'The total of two variables  = ';

print ($connect_text . $total);

?>

</body>
</html>

then,let us take a look on this line :

$total = $number1 + $number2;

here ,we got 3 variables ,1 '=' and 1 '+'.so this plus symbol(+) is function to add the variables.

plus it also can be like this:

print(10+20+30);
print($number1+10+$number2);

well,just try change '+' with other operation symbol like subtract(-),divide(/) and multiply(*).then take this line:

$total = $number1 + $number2;

change it to be like this:

$total = $number1 + ($number2-$number3);
/*remember...to declare first the variable '$number3' and already put the value in that variable*/

N/NOTE:Well,just explore it by urself,if got some problem,please comment me...

      --->operation in PHP is piece of cake !<---
