| 1.1 | 44 | Show intermediate results
|
| 1.6 | 20 | Explain why or why not, specifying rules of inference/fallacies.

| 1.8 | 8+addition | Read carefully. It says "not exceeding it", so the number itself should be included. The addition is to answer the same problem, but with the phrase "not exceeding it" replaced with "less than it".
|
| 2.2 | 12 | Use a "set containment proof". See Examples 10 and 12. Your proof should contain phrases like "Let x∈FOO", "by the definition of union", "thus FOO⊆FERZLE", etc.
