Computations

To evaluate mathematical expressions in user input fields and other mathematical expressions, edML uses a Computer Algebra System (CAS). This part of the documentation describes the properties of the CAS used in edML.

The edML language does not specify the exact CAS that is used. The edML player currently uses the CAS Nerdamer, which has the advantage that it runs in the browser using JavaScript. Therefore, the syntax of expressions in edML closely follows the syntax in Nerdamer.
