DragMath is a drag-and-drop equation editor originally developed by Alex Billingsley, under the tutelage of Chris Sangwin, at the University of Birmingham in the UK.
You can see that it looks very similar to the equation editors we first introduced in Chapter 2. However, as you can see, DragMath fully integrates into Moodle. It was originally part of a computer algebra system called STACK, which we introduced in Chapter 6. More details on DragMath can be found in the Moodle docs (http://docs.moodle.org/en/DragMath_equation_editor).
Let's start by installing DragMath. You'll need Moodle administrator privileges, and you'll need access to the server Moodle is running on. If you don't have either, then hand this book over to your Moodle administrator now.
