Wants to merge their version, Ulrich's copy of Arithmetics of complex numbers V .In part d) the expected answer should be {i^rem} not {i^n} because the latter, while "mathematically" the same, leads to floating point number issues when revealing the answers (it shows something like, e.g., "Expected answer 1 - 5047/2104i*10^(-12)" instead of "1" (in case rem==4).
I hope that this is the appropriate way to submit this comment.

Error in variable testing condition
There's an error in the variable testing condition. Variable values can't be generated until it's fixed.
No variables have been defined in this question.
Generated value:
- :
This variable doesn't seem to be used anywhere.
No parts have been defined in this question.
Select a part to edit.
This gap is not used in the parent part's prompt.
The student will not be able to enter an answer to this gap.
Ask the student a question, and give any hints about how they should answer this part.

String restrictions
For each combination of answer and choice, specify the number of marks to add or subtract when the student picks it.
For each combination of answer and choice, write 1 if the student should tick it, or 0 if they should leave it unticked.
Test that the marking algorithm works
Check that the marking algorithm works with different sets of variables and student answers using the interface below.
Create unit tests to save expected results and to document how the algorithm should work.
There's an error which means the marking algorithm can't run:
This is an extension type part. There is no expected answer, and it's assumed that the marking depends on interactions within the part's prompt.
You can test this part's marking algorithm by interacting with the rendering of the part's prompt below.

This test is not currently producing the expected result. Fix the marking algorithm to produce the expected results detailed below or, if this test is out of date, update the test to accept the current values.
One or more notes in this test are no longer defined. If these notes are no longer needed, you should delete this test.

When you need to change the way this part works beyond the available options, you can write JavaScript code to be executed at the times described below.
To account for errors made by the student in earlier calculations, replace question variables with answers to earlier parts.
In order to create a variable replacement, you must define at least one variable and one other part.
| Variable | Answer to use | Must be answered? | |
|---|---|---|---|
The variable replacements you've chosen will cause the following variables to be regenerated each time the student submits an answer to this part:
These variables have some random elements, which means they're not guaranteed to have the same value each time the student submits an answer. You should define new variables to store the random elements, so that they remain the same each time this part is marked.
This part can't be reached by the student.
Add a "next part" reference to this part from another part.
None of the parts which can lead to this part are reachable either.
