Essay question:

Suggestions for writing: If you explained your solution to an essay question to your roomate or to your family, you would use words and sentences to communicate. Think of your write-up of these questions as a transcription of these conversations. Describe the problem and your response to it in a way that reads like a page from a textbook.

I made some copies of an example of an 'essay' style write-up of a homework question. It is in the box outside of my office. It is also available online here.

Question due 6/25: Example 3 on p. 202 shows that a three element set has eight subsets. (Note that if A is a set, both the empty set and A itself are counted as subsets of A.)
How many subsets does a two element set have? What about a four element set? Can you find a pattern? How many subsets does a set with n elements have?
