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 Bin
A measurement is performed multiple times for the same object, the student will
- calculate the mean result
- calculate the standard error on the mean
- write the mean±error to the correct precision as defined by the error written to 1 significant figure
Advice is provided including on performing the calculations in Python or spreedsheets together with further reading.

Question in TALMO Formative assessment talk 2022
Made for my TALMO talk. This demonstrates how you can use a part with no marks as an oracle to perform calculations, to help the student check their working.

Question in Julia Goedecke's contributions
Educational calculation tool rather than "question".
This allows the student to input a linear system in augmented matrix form (max rows 5, but any number of variables). Then the student can decide to swap some rows, or multiply some rows, or add multiples of one row to other rows. The student only has to input what operation should be performed, and this is automatically applied to the system. This question has no marks and no feedback as it's just meant as a "calculator".
It has some rounding to 13 decimal places, as otherwise some fraction calculations become incorrectly displayed as a very small number instead of 0.
It would be possible to extend to more than 5 rows, one just has to put in a lot more variables and so on. I just had to choose some place to stop.

The student only has to input what operation should be performed, and this is automatically applied to the matrix and the identity matrix (or what it has got to). This question has no marks and no feedback as it's just meant as a "calculator". It has some checks in so students know when they are not entering a square matrix or a valid row number etc.
