I am using version 2.8.6. In a calculated multichoice question, how can you account for choices that may or may not be correct, depending on the values of the wildcards?
Example:
Q: What is {x} + {y}?Answer choices:
a) {={x}+{y}}b) {={x}-{y}}
c) {={x}*{y}}d) {={x}/{y}}Answer (a) is meant to be correct, but with some wildcard values (such as when x=2 and y=2), answer (c) is also correct. Does Moodle somehow recognize the value of the correct choice (a), and then detect that (c) is equal to that value?
