|How Can I Enter Chemical or Maths Symbols?
You can enter most symbols and equations using the HTML formatting feature. The formatting allows subscripts and superscripts which are particularly useful for mathematical and chemistry formulae. See Text Settings to learn how to include HTML formatted text.
If you need to enter symbols which are not included in the current HTML set, you can write your equation using some other software eg in MSWord and then take a snapshot. You can then load this image to the question. For more information on adding images see Adding Questions.
