Hi Christopher,
Thanks for the calculator.
By chance, do you have the Generico Filter installed? For anyone who does, you can make it simpler to add the calculator anywhere you can edit in Moodle.
Instead of having to keep track of a copy of the iframe stuff listed in your previous post, Generico can do that for you. Then it becomes three simple clicks (click the Generico toolbutton, click the calculator filter option, then click Insert) to add your calculator wherever you need it.
Recently, Justin Hunt modified the Generico Filter add-on to make it very easy to exchange filter templates. There a number of them (post-it, flow chart, prettify, countdown, etc) available in this forum post:
