### Hardcopy

If you'd like to get a hardcopy printed, you can get it done at the Interurban Satellite Printshop in the CBA Atrium (hours given in the link) – just ask them to print the "Math 155 Course Materials" for you, since they should have the URL on file.

### Corrections

- Section 2.4: In the last example of 2.4.2 on page 85, the answer has been corrected so that the negation bar is above the entire expression – the PDF has been fixed.
- Section 2.6:
- In the Exercises section, question 44 should be AB + not(AB)C – the PDF has been fixed.
- In the Exercises section, question 49 should be "A (not B) not ((not A) (not C)) = A (not B) – it's easier to read in the PDF, which has been fixed.

- Section 3.2:
- In the first example under 3.2.3, there is an extra 6 underneath the 18.
- In the summary at the end of the section, 3.2.5, the second expression for S
_{k}should have had a_{m}in the expression instead of a_{1}. - In the exercises, the first number in question 9 should be -40, not 40.
- In the exercises, questions 33, 35, and 36 needed to have some extra brackets around the expression to the right of the sigma.

- Section 3.3: In the Exercises, the first term in question 9 should be 3, not 2. The answer to that question has also been fixed.
