This question type allows asking questions such as :
Please enter X, Y, and Z, such as :
- X + Y + Z > 12
- X - Y <= 3
- Z = [0;100] (Z is between 0 and 100, included)
For each constraint, a feedback can be generated, displaying some text for a condition being fulfilled, and some other text if not.
The grading can be set to be one of the following :
- 100% (all constraints fulfilled) or 0%
- grade = (amount of constraints fulfilled) / (total amount of constraints)

In PHPMyAdmin you have to click the "structure" button next to the table name (or on top of the screen once the table is selected) to see the structure. It is possible that the table contains no records (i.e., no rows) but it is the structure of the table (not its content) that matters here.
I have 8 fields: id, question, parameters, conditions, feedbackperconditions, binarygrade, displaycalc and usecolorforfeedback.
So no questionid, but there is id.
Okay, there is apparently an upgrade path I didn't think of. To solve your problem, you can safely delete line 50 of the multinuerical/db/upgrade.php file. Then the upgrade process should be able to finish correctly.
Thank you,

Thank you,
I've just come across this question type and am interested in using it to set multi-part calculation questions where any calculation errors on the part of the user are carried forward and taken into account in their next answer.
It seems to work where the answers are whole numbers, but falls down where irrational numbers are concerned. I'd like to be able to set a tolerance on correct answers but haven't found a way to do it. I was thinking that Boolean operators might work but they don't seem to be recognised. Is that right? Is there any other way to do this that you can think of?
I'm not sure to understand precisely what you're trying to achieve, but intervals for correct responses can be defined, i.e.:
X + Y = [57;62]
There's no way to use boolean operators. If you feel like PM'ing me some more details, I can try to think of something.
Any updates do Moodle 3.4?

I didn't test extensively, but this should work on 3.4.
Thanks again for your work on this software--it's transformed my science classroom. After using the plugin extensively with my classes, I have a few suggestions to make it even better:
1) Create an option to automatically mark zeros or blank parameters incorrect. Right now it is possible for a student to score points by leaving input boxes blank (as many operations involving 0 will return 0).
2) Allow the display of custom text by the input box, instead of the parameter name.
3) More options for grading (e.g. some constraints may be worth more than others)
4) Allow the user to set a tolerance for each parameter (right now I am accomplishing this by using the range function, but it is awkward)
Thanks again!

Thanks for your feedback!
1) What about if zero is a correct answer? Can you describe when it is possible to score points when it shouldn't?
2-4) Good idea! Thanks for the suggestions, I'll try to implement this.
