A graph (of a cubic) is given. The question is to determine the number of roots and number of stationary points the graph has. Non-calculator. Advice is given.

Given an ascending sequence of numbers, finds the index in the sequence of the first number greater than or equal to a given value.

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.

Pick from the range -5..5, but make 0 more likely.

Demonstrates how to set up a "choose one from a list" part where the number of choices is randomised.

The part is given a list of labels for the choices as well as a list specifying the marks to award for each choice.

Should not be used: there's now a built-in function frequencies.

This question randomly generates a list of 100 items, each chosen from a list of strings.

It then computes the number of occurrences of each distinct item in the list. The statement shows the frequencies in a table.

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.

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.

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.

Ask for the squares of five randomly-chosen numbers between 0 and 15.

The shuffle function puts a list in random order.

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

Do not use this: alternative answers are the best way of accepting multiple correct answers.

A couple of different ways of asking the student to enter a large number, to get around the floating point imprecision problem.

Given some random finite subsets of the natural numbers, perform set operations $\cap,\;\cup$ and complement.

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