There is no value for your select(action). So it's posting blank, try to Assign a value attribute to your options

<option value="+">+<option>
<option value="-">-<option>
<option value="*">*<option>
<option value="/">/<option>

<select name="action">
   <option value="+">+<option>
   <option value="-">-<option>
   <option value="*">*<option>
   <option value="/">/<option>
</select>
