First create a module named mymodule(You can name it whatever you want). The path will be Home/app/code/local/Test/Mymodule.
1. Add the below in within the global tag in Home/app/code/local/Test/Mymodule/etc/config.xml

<helpers>
<mymodule>
<class>MyExtensions_Mymodule_Helper</class>
</mymodule>
</helpers>

2. Create a file Home/app/code/local/Test/Mymodule/Helper/Calculator.php

<?php
class MyExtensions_Mymodule_Helper_Calculator extends Mage_Core_Helper_Abstract
{
public function add($a, $b)
{
return $a + $b;
}

?>


You can call the helper in following way

$result = Mage::helper('Mymodule/Calculator')->add(2,3);


Here $result will have value returned from helper.
