Allow a "multiple numerical" question type
This would be a question where students could enter in a sequence of numbers of specified length. For example, if I want students to enter in the components of a vector in R3, it would give them three blanks into which they type numbers. Again, like the existing "numerical" type but with multiple blanks (the number of which is determined when the question is created).
A workaround for now is to use an expression question and have students enter the vector components in ijk notation, e.g., i – 2j + 3k for (1, -2, 3).

There is a related suggestion to create a Question Type "Fill in a table".
