When documenting the steps taken to simplify a budget-related expression in a financial report, an analyst organizes the work vertically. According to standard professional best practices, what is the primary reason the analyst should omit equal signs between the successive lines of the simplification?

A procurement officer is documenting the simplification of the expression $4 \cdot 2 + 1$ in a supply report. Following the professional best practices of vertical organization and omitting equal signs as described in the course, which of the following should appear on the line immediately following the original expression?
