Question in Foundation Maths
Show one of several blocks of text depending on the value of a question variable.
As well as a simple check for the value of a variable, the condition to display a block of text can be a complex expression in any of the question variables - in this example, depending on the discriminant of the generated quadratic.

Question in Musa's workspace
$x$ is given and (sin(x),cos(x)) is plotted on a unit circle. Then the student is asked to determine sin(y) and cos(y), where y is closely related to x (e.g. y=-x, y=180+x, etc.) Also find values and sign of cos/tan/sin(x).

Question in Programming extension
Given a randomly-generated list, the student must write code to return its first value.
There's an alternative to check if they get the second item, which they might do if they don't realise Python lists are zero-indexed.

Question in MESH
Students are asked to move an x-axis slider representing standard deviation on a normal distribution to make the area between (mean - slider value) and (mean + slider value) equal to a certain percentage. The 3 possible percentages correspond to the mean plus or minus 1, 2 or 3 standard deviations.

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.

Question in How-tos
The answer to this question is a differential equation involving $y''$, $y'$ and $y$.
A variable value generator for $y$ ensures that the right values are tested to check that the student's answer is equivalent to the expected equation.
