The student is asked to find the square root of an integer of the form ±n2. 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

Issues: alignment in columns in the working - not sure what to do about it
Decimal divided by a decimal. Multiply by a power of ten to get an integer divisor. Long and short division process. There is a remainder which we express as a decimal by continuing the division process. Rounding is required to some number of decimal places.
-
Divisor is a two-digit number. There is a remainder which we express as a decimal by continuing the division process. Rounding is required to one decimal place. The working suggests determining the second decimal place so the student knows whether to round up or down.

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.
