Can I create a Calculator with HTML?

[rse2]

Are there variables that I can use to for example create a calculator? Or can i only do that with java script? Is it possible to make a form to fill with HTML, that will calculate the answer?

 <form name="calc" ACTION="1.calc"  METHOD="post">

<select NAME="first number" size="1">
<option SELECTED VALUE="">
               <option VALUE="1">one</option>
               <option VALUE="2">two</option>
</select>

<select NAME="Operation" size="2">
 <option VALUE="Add">Add</option>
               <option VALUE="Sub">Subtract</option>

Is Sub the variable of Subtract?

HTML is not a programming language so you can't do any of that. Javascript can.

Code tags are used with square brackets. []
