I am wondering if a graphic box or visible space is best to be used in the examples attached. This is a 1st grade workbook (not textbook), expendable project and rule 10.1.1 h-i does not specifically include these scenarios since it is a linear math equation. If a graphic box is to be used, what size and spacing is best?
Since the examples you are referring to Mathematical Equations, I think this question is best answered by either the UEB technical or Nemeth Experts depending on the code you are using.
Please repost this question on one of their forums. I am sure you will get an excellent answer.
