Dear Tim Hunt,
I'm creating questions in which numerical answers are required and want to show the answer in the General feedback field, so my pupils may see a fully worked-out solution including the answer. Can this be done? For example, using {i} as a wildcard and entering {i}/1000 in the Answer 1 formula box, how can the answer be shown to the pupils after they click on Check?
Imagine the computer generated wildcard {i} is a number such as 12. The correct answer is 0.012. What command (LaTeX or Sprintf or whatever) should I place in the General feedback field to elicit the expected answer, that is, 0.012. (Entering {i}/1000 simply doesn't work and entering \frac{{i}}{1000} just doesn't look as it should, as you can see in the attached screen-print.)
Thanks for your answer,
Al
