Logical operators

The following logical operators can be used in Ans:

  • a && b : a and b need to be on the same line, but the order is not important. 
  • a $$ b : a and b need to be on the same line and in the given order.
  • a @@ b : a and b can be on different lines, but have to be in the given order. 
  • a || b : a or b. 

Examples

  • (a && b) || (a $$ b) : combinations always have to be in brackets. 
  • (a) || (a $$ b) : combinations always have to be in brackets. 
  • a = b * c    can be written as: 
    (a) $$ (=) $$ (b && * && c)

What’s next
You are able to upload an attachment. These can be used as an attachment for staff or as an attachment for learners. By default, the attachments are hidden from learners, they are only visible to staff. They can be made visible and then learners can see these at the page of the assignment.
