The primary purpose of this task is to illustrate certain aspects of the mathematics described in the A.SSE.1. The task has students look for structure in algebraic expressions related to a context, and asks them to relate that structure to the context. In particular, it is worth emphasizing that the task requires no algebraic manipulation from the students. Parts (a) and (b) of the task directly illustrate A-SSE.1a, and parts (c) and (d) are similar, but are intricate enough expressions that students are likely to make progress only by parsing the expression into simpler parts and interpreting them one at a time.
