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

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

it does not state what the problem is;

it does not explain what the variables stand for;

the computations come without explanations of their purpose,

the work jumps around on the page instead of following linearly down the page; and

the answers don't stand on their own.

Compare this with a well-written homework assignment.
