<input type="text" id="textBox1"/><br/>
<input type="text" id="textBox2"/><br/>
<input type="button" value="ADD" id="addNumbers"/>

var tempVariable ='';
$("#addNumbers").click(function(){
var a = $("#textBox1").val();
var b = $("#textBox2").val();
tempVariable = parseInt(a)+parseInt(b);
alert(tempVariable);
});

For the demo you can check the fiddle below:

Here the parseInt does the trick, try now adding without parseInt then see the difference.

This will be of sure help I hope.

Thanks
