Thank you for your question! Before we respond in full, could you please share two clarifying pieces of information?

First, what is one specific lesson manual or code book that says, “nested linked expressions are displayed material”?

Second, what is your reasoning for having blank spaces in some places but not in other places (e.g., between the word “tenths” and the symbol ÷ but not between the symbol ÷ and the underscore)?
