Question in HELM books
There are two parts:
(3x)/4-x/5+x/3 and (3x/4)-(x/5+x/3).
The numbers are randomised to small, coprime, positive integers.
-
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 Demos
Shows how the "give a number which satisfies an equation" part type can be used to makr the student's number correct if it satisfies an equation of the form $f(x) = 0$.

Question in Demos
In the first part, the student must write an R function to compute the first $n$ terms of the series $\frac{1}{k!}$.
In the second part, they must use that function to calculate an approximation to $e$ using a given number of terms of the series.

Question in Maura's workspace
This question tests students' ability to use repeated squaring to perform modular exponentiation. Moduli are random numbers between 30 and 70, the base is a number between 10 and 29. To generate questions of approximately uniform difficult the exponent is taken to be 256 plus two smaller powers of 2.

Question in DemosAn interactive experiment about probability: the student must first 'design' the experiment by deciding how many times they're going to flip a coin, and define what number of heads would make them believe the coin is biased. They must then enter the results of their coin flips, calculate the percentage of heads, and finally decide if the coin is biased, using the condition they specified in the design stage. There are optional hints at each stage.
