This question asks a student to draw a straight line graph by dragging points.

Questions on addition, subtraction, multiplication and powers of negative numbers.

This is a Numbas test for parametric hypothesis tests with psychology content. To be used in the mathematics wiki page.

Practising calculations with percentages and ratios.

Because JavaScript numbers lose precision as they get bigger, you get some unexpected results.

See the variable "two" - the difference should be 2, but because the JavaScript representation of each of the two numbers is the same, it thinks the difference is 0.

Using the decimal data type, there's no loss of precision, so the correct value is produced.

This question uses the vis.js library to plot 3D functions and data sets.

As well as JME functions to make plots, you can use javascript functions to get more control over how the plots are rendered.

Give the student a larger area to write some free-form text, which isn't marked.

Shows how to use the JME function lpad to add zeros to the beginning of a number so it's always displayed using two digits.

This exam uses a custom theme to provide no feedback about scores to the student.

The idea is to provide a version of the test compiled with this theme to the students as they attempt it. Once the test has closed, update with a version of the same test compiled with the default theme, so students can go back in and get feedback.

The student is asked to write a number with a certain property, or tick a box labelled "this is impossible" if it can't be done.

A custom marking algorithm on the gap-fill part first checks if the student ticked the box. If they did, their answer is marked correct if it really is impossible. If they didn't tick it, their number is checked against the required property.

Demo showing how to write a custom function in javascript.

This shows how to implement a recursive function in JavaScript with a nested function definition.

This demonstrates how to render a set of tuples such as $\{(1,2),(3,4)\}$ in LaTeX, starting with a list of pairs of numbers.

This question shows how to use the currency function to display amounts of currency with the correct symbols.

This question shows how to display a number like "1234" as "1,234", or "1 234", using the formatNumber function.

A randomised table is contained in a div tag with the id #sales-table, so it can be styled using the CSS preamble.

Simple probability question. Counting number of occurrences of an event in a sample space with given size and finding the probability of the event.

Find moment of inertia of a composite shape consisting of a rectangle and two triangles with respect to the x-axis. Shapes rest on the x-axis so the parallel axis theorem is not required.

Quiz covering basic arithmetic with complex numbers, solving a quadratic with complex solutions and converting to/from polar and rectangular forms.
