Two functions given in words. Write down the function definition. The numbers in the function definitions are randomised.

Practice MCQ to decide which quadrant a complex number lies in.

The student is asked to find the square root of an integer of the form $\pm n^2$. If the root is not real, they should enter "nan".

A custom marking algorithm extends the built-in one to deal with "nan".

There's some custom javascript to set the expected answer correctly. In the future this will be possible in the marking algorithm - see https://github.com/numbas/Numbas/issues/856

Multlipying and subtracting mixed numbers. It is expected that a calculator is used to perform this question.

A whole number divided by a very simple algebraic fraction. No cancelling is required by design.

A very simple algebraic fraction multiplied by a whole number. No cancelling is required by design. 

A question which asks students to encrypt a number using RSA, then to factor a small public key and find the decryption exponent.

This question aims at getting the students to demonstrate their ability to apply the Euclidean algorithm to find the GCD between two numbers.

We provide two randomly generated numbers and ask the students to enter the steps of the Euclidean algorithm, as well as the GCD between the numbers.

Counting the number of significant figures. 

Example showing how to mark a "choose one from a list" part where the student has to pick the range a given number lies in.

In the first part, the student is asked to enter dimensions of a box in a spreadsheet.

The values are extracted as a list of numbers by changing the interpreted_answer note in the first part's marking algorithm, and the calculated volume is used as the answer to the second part, through adaptive marking.

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

This demonstrates how to:

• Generate a fixed number of observations of data in two categories.
• Display the data in a table, with row and column totals.
• Ask the student to enter the data in a spreadsheet which is automatically marked.

Elementary examples of multiplication and addition of complex numbers. Four parts.

In class test contributes about 30% of your assesment work. Make sure you write your REG number.

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.
