Enter Purdue ID and password. After logging in, click "actions" and select "edit". Then make the requisite changes in the editor you will see. Then click "save page" all the way down. Check that you wrote what you wanted.
Do not delete or edit previously listed typos.
Please list any typo found in the course notes below. Mimic the first two entries: indicate page, line from above (positive numbers) or from the bottom (negative numbers), old text and new text. Add a new line for each typo.
- 1. list here the first typo
- 2. and here the next
- etc.
- Not a typo, but a note. The way that the chapter numbers change with both a change in chapter and a change in section is very confusing especially for when trying to find the hw problems. (For example: Chapter 2 Arithmetic, 1. The Integers, 1.1 Prime Numbers, Definition 2.1 ... , with 2. Arithmetic and 1. The Integers then alternating at the top of the page)
- 1. page 22, 1st line. Original text reads "$1.000.000 to crack it". English convention is to use "," for digit grouping and "." for decimal marks. New text: "1,000,000 to crack it."
- 2. page 27, line 3-6. In line 3 you state that n=10, then have it substituted in line 4 (Z/10Z), go back to using n in line 5 (Z/nZ) and then finally use 10 again in line 6.
- 3. page 52, the coefficient of 3rd term after colon of THEOREM 4.12(Binomial Theorem) is not correct.
- 4. page 54, line 3. there are two "the" before the word "separators".
