| 0 comments

Version 8.0 of exerquiz introduces the features in the title of this article. The \RespBoxMath command allows for multi-letter variables (‘theta’, for example, to represent an angle). Alternate appearances refers to the feature where the variables are replaced by other symbols, when the user leaves the field; for example, ‘theta’ may be replaced with \u03B8, unicode for the Greek letter theta. Interval repetition refer to a new notation [0,1]*3 as a short-hand notation for [0,1]x[0,1]x[0,1].
