### Homework Assignment

Directions

• Give a sentence or two explanation for all answers. Correct answers without explanation may not receive full credit. If you are not sure what to say consider the following.
• Restate what the set is in words rather than mathematical notation. For example if you are working with a set X = {n ∈ ℕ : n is even} you could say "The set X contains all even integers larger than zero".
• Restate a relevant definition. For example if you are finding the union of two sets mention that the answer contains all elements from both sets.
• If you received significant ideas from another person or worked with another person please acknowledge them at the end of your homework or homework problem.
