As significant mathematics errors appear, they will be logged here. Most of the typographical errors (missing/extraneous spaces, mathematics in non-math font, etc.) are not listed.

**Introduction**, In Figure .0.6 (The 3-cube) there should not be an edge connecting 010 to 101. (Already fixed in the html version)**Section 1.2**, Problem 4, part (d): The equality $A \oplus (B\cap C) = (A \oplus B)\cap (A \oplus C)$ is not always true. For example, if $A = \{1\}$, $B = \{1\}$, and $C =\emptyset$, then the left hand side of the identity is $\{1\}$ while the right hand side is the empty set. Another example is $A = \{1,2\}$, $B = \{1\}$, and $C =\{2\}.$(found by Jim Propp)**Section 3.8**The answer to exercise 1(a) should be $(\forall x)(F(x)\to C(x))$. (Found by Maksim Mints, UML Student)**Section 9.6**, Problem 3(a) the solution that is given is incorrect. It should be 4, not 3, since the graph in this part is a $K_4$. (found by Jeremy Joubert, UML student)**Section 12.1**The solutions to parts (a) and (b) of exercise 3 are incorrect. They should be- $\{(1.2+5x_3, 2.6-4 x_3, 4.5) \mid x_3 \in \mathbb{R}\}$
- The solution set is empty
