Writing Multiple-type answer Questions

Multiple-type answer questions are widespread in Otter Math. We need them in the ratio of 70% Multiple Choice and 30% Input questions. 

Multiple-type questions have one Math problem and several answer options from which the user sets the correct one. You fill in the correct and wrong answer templates using Otter programming language to set correct calculations for correct answers, and wrong calculations for wrong answers. 

Let's imagine a calculation for our Multiple-type question.

For the correct answer you use the value that you have beforehand marked as the correct result:

And for wrong answers you use the value that you have beforehand marked as the wrong result:

There should be 4-5 options for wrong answers, so don't forget to store more wrong values or to use functions that will ensure your values are unique. By that I mean that they will ensure that 301 and 301 will never be repeated on your wrong answers list as a wrong answer twice in different boxes.  

There are functions in the Otter programming language to calculate everything you need. To know more about them, read the next page.
