Question in How-tos
The student is asked to give the roots of a quadratic equation. They should be able to enter the numbers in any order, and each correct number should earn a mark.
When there's only one root, the student can only fill in one of the answer fields.
This is implemented with a gap-fill with two number entry gaps. The gaps have a custom marking algorithm to allow an empty answer. The gap-fill considers the student's two answers as a set, and compares with the set of correct answers.
The marking corresponds to this table:
There is one root There are two roots Student gives one correct root 100% 50%, "The root you gave is correct, but there is another one." Student gives two correct roots impossible 100% Student gives one incorrect root 0% 0% Student gives one incorrect, one correct root 50% "One of the numbers you gave is not a root". 50% "One of the numbers you gave is not a root". Student gives two incorrect roots 0% 0% -
Question in How-tos
A custom marking algorithm picks out the names of the constants of integration that the student has used in their answer, and tries mapping them to every permutation of the constants used in the expected answer. The version that agrees the most with the expected answer is used for testing equivalence.
If the student uses fewer constants of integration, it still works (but they must be wrong), and if they use too many, it's still marked correct if the other variables have no impact on the result. For example, adding $+0t$ to an expression which otherwise doesn't use $t$ would have no impact.

Question in Christian's workspace
The student is asked to calculate a division by the method of long division, which they should enter in a grid.
The process is simulated and the order in which cells are filled in is recorded, so the marking feedback tries to identify the first cell that the student got wrong, or should try to fill in next.
They're asked to give the quotient as a plain number in a second part, to check that they can interpret the finished grid properly.

Question in Maura's workspace
A straightforward test of encrypting and decrypting an eight-letter message with the Vigenère Cipher using a four-letter key. Message letters are generated uniformly at random from the English alphabet, as are the key letters. Students are expected to be able to map English letters onto elements of $\mathbb{Z}_{26}$ in the usual order.

Question in Maura's workspace
A straightforward test of encrypting and decrypting an eight-letter message with the Substitution Cipher. Message letters are generated uniformly at random from the English alphabet and the key is a uniformly chosen random permutation of the alphabet. Students are expected to be able to map English letters onto elements of $\mathbb{Z}_{26}$ in the usual order.

Question in Demos
All the answers in this question are equations. In order to mark each equation, Numbas needs to pick some values that satisfy the equation and some that don't, and check that the student's answer agrees with the expected answer.
Any equation with the same solution set as the expected answer will be marked correct.
