A well-written homework assignment
(as opposed to a poorly written one)

Here is an example of a well written homework assignment. Notice that

(a) It starts with a summary of what the problem is.

(b) The diagram is large, and is labeled with both variables and words.

(c) It explains what the purpose of the succeeding computations are.

(d) When a new set of computations begin, it explains what those compuations are for.

(e) It ends with a statement of the answer which stands on its own.

Compare this with a poorly written homework assignment.
