I am using algorithmic variables to generate questions about the greatest common divisor of two integers.

Unforuntately the integers come out as 1,664 instead of simply 1664 (for example). How can I change the format to the simple version ?

Thanks for your help!


I’m pleased to announce the release of Maple T.A. 2016.

For this release, we put a lot of effort into streamlining the authoring experience. We worked closely with customers to find out how they authored content, the places where they found the interface awkward, the tasks that took longer than they should have, and what they’d like to see changed. Then we made it better.

Right away you’ll notice that questions and assignments are no longer in separate places in Maple T.A. All your content is stored in a convenient location that makes it simple to browse your content. Contextual navigation, filtering options, sorting tools, question details, drag and drop organization, combined import feature, and more make it easier than ever to find and organize your content. The Maple T.A. Cloud also sees improvements. Not only can questions be shared, but assignments and entire course modules can be as well.

For question creation, we consolidated all question authoring into the question designer, so you have a single starting point no matter what kind of question you want to create. We have also refined the text editor to help authors find the tools they need to modify their questions. This includes embedding external content, importing questions from the repository, text formatting options, and more.

Of course, once you have questions, you’ll want to put them into an assignment, and assignment creation is now easier than ever. A key change is that you can now create and modify questions while you are creating an assignment, without having to leave the assignment editor. There are also changes to how you preview questions, set properties, and even save your assignments, all of which contribute to making assignment creation simpler and faster.

Of course, there’s more than just a significantly improved author workflow. Here are some highlights:

  • Assignment groups for efficient organization, both in the content repository and on the class homepage.
  • Easy-to-create sorting questions – no coding required!
  • HTML questions, which can be authored directly in the question designer.
  • Clickable image questions are Java-free and easier to author.
  • Maximum word counts and other improvements to the essay question type.
  • A new scanned document feature lets instructors upload and even grade scanned documents.
  • Officially certified LTI integration for connectivity with a wide range of course management systems

See What’s New in Maple T.A. 2016 for more information on these and other new features.

I'd like to create a graded drag and drop exercise so that my students can click on an item and place it into various places (one of which is the correct place). I don't think any of the Question types support this though .. is there a way to build such a quesiton in Maple TA ?

Thank you for your help!


Is it possible to work with complex numbers in Maple T.A?

How could you for instance make a question where two complex numbers in polar form should be added. For instance (10<30deg)+(15<-10deg). I'm thinking of letting answers be in two fields, one for the absolute value and one for the angle but I would like to use random numbers in the two complex numbers to be added and would prefer to be able to use complex math in calculating the right answer.

Dear All,

I use Maple T.A. 10. I try to use StringTools[Search] in algorithm variables but have not succeeded. Any help would be appreciated.

Algorithm Variable definitions


give us the following result, whereas I expect the return value 1.

I confirmed that one can use StringTools[Search] in the question source code as explained in

maple=evalb(0=StringTools[Search]("factor","$RESPONSE")) and evalb($RESPONSE=factor(x^2-1))

I note that searchtext or SearchText procedures could be used instead in algorithm variables.

I try to make a question with an equation with numbered variables. This works fine when evaluating:


I need to have the lefthand variable indexed also like this:


When entering y2=x1/x2 as the answer Maple TA won't evaluate it as a correct answer!?

Um den Studierenden zu helfen, deren Mathematikkenntnisse nicht auf dem von Studienanfängern erwarteten Niveau waren, hat die TU Wien einen Auffrischungskurs mit Maple T.A. entwickelt.  Die vom Team der TU Wien ausgearbeiteten Fragen zu mathematischen Themen wie der Integralrechnung, linearen Funktionen, der Vektoranalysis, der Differentialrechnung und der Trigonometrie, sind in die Maple T.A. Cloud übernommen worden.  Außerdem haben wir diesen Inhalt als Kursmodul zur Verfügung gestellt.

Laden Sie das Kursmodul der TU Wien herunter.

Assume the inequality xA,2+xB,2+xC,2 ≤ 110 has to be entered as "symbolic entry only".

How can I check that in Maple T.A.?

It seems that there are type conversions necessary. I attempted to use the MathML package without any luck.

  1. Tried to transform $ANSWER within the answer field using MathML[ExportPresentation]( x[A,2]+x[B,2]+x[C,2] <= 110) and compare it with evalb(($ANSWER)=($RESPONSE)) in the grading code field
  2. Tried to transform $RESPONSE in the grading code: evalb(($ANSWER)=( MathML[ImportContent] ($RESPONSE)))

What’s the format of a symbolic entry? Is it really MathML!?

What is the correct way to do it?

  1. answer: ?
  2. grading code: ?
  3. expression type: Maple syntax?!
  4. Text/Symbolic entry: Symbolic entry only

Assume you want to check that the following inequality was correctly derived:

xA2+xB2+xC2 ≤ 110

How can I check that in Maple T.A.?

If I use a Maple-Graded questions, what must be in the answer field? x[A,2]+x[B,2]+x[C,2] <= 110 !?

What is the grading code?

How do you check an indexed variable in Maple TA?

For instance the question might be: enter 6x1   (or 6xA1)

I have tried using a Maple-graded question specifying as correct answer 6*x[1]   (or 6*x[A,1]) without any success (works only for 6x).

I have written a Math App in Maple to create a Math App question in Maple TA.

The app has two tables, a plot area, and text box. The first table provides the data to the students for calculating their answer (and so Editable in the component properties is unchecked). The second table is where the student enters their answers (and so Editable is checked). The text area and plot area are for providing some real time feedback and error checking to the students.

Everything works fine in Maple.

In Maple TA I have tried using both a Math App question type and a Question Designer question type with a Math App inserted. I have tested it in Internet Explorer, Chrome and Firefox.

In all six cases when I click on one of the editable table cells to put in an answer a popup appears with the error message: "Unable to update RTable due to error=TypeError: window.parent.parent.updateRTable is not a function"

I am using Maple 10 and the latest hotfix is SP-002.

What I have worked out so far is that the Maple TA web page is designed so that the Math App sits in an iframe and each table sits in a separate iframe inside that iframe. updateRTable is a function inside the tables iframe that calls the updateRTable on the top level window and if this fails gives the error message above.

The top level window includes the file /maplenet/js/worksheet.js, which includes the function updateRTable.

How do I fix this error?

I am writing here because of a problem with writing mathematical expressions in Maple T.A.. I have been using it since two years, and I have a lot if questions created in version 9.0 and 9.5. A few months ago my university installed T.A. 10. At the beginning there were problems with the connections between T.A. and the Maple server. After the administrators got over these, there were another problems.

There are a lot of questions where I use greek letters, for example Sigma. Earlier it was easy, I wrote

in the 'Algorithm' section, and I could write

in the Text of the question. The letter had a perfect italic and bold style, like as it would be created with Equation Editor.

Now I have to write


Maple T.A. 10 introduced two new question types: Sketch and Free Body Diagram. To assist users in learning the new question types, Maplesoft has created a few hundred samples to look at. These sample questions are already featured on the Maple T.A. Cloud, but you can also download the course modules below. 

Sketching Questions - This course module contains 309 sketch questions. Areas covered include: functions, exponential functions, inequalities, linear equations, logarithmic functions, piecewise functions, quadratic equations, systems of equations and transformations of functions.

Free Body Diagram Questions - This course module contains 118 free body diagram questions. Areas covered include: Electricity, Magnetism and Mechanics.
