p32 #15  3^rd Equation should have “+x_1” instead of “-x_1”

• p73 #25(d) is -> be

• p82 #12a  Should be ... 7B^2...  i.e. B squared.

• p83 #35 Should be ... + x3... in the first equation. (+ not -)

• p167 last line on page is missing a 3 inside the parentheses, before the first determinant

• p200 axioms 5 and 6 are grammatically unclear: should either say “there exist a unique”, etc. or use “a” instead of “the”

• p203 the definition at the bottom of the pg: the last sentence is unclear because the existence of a 0 vector is not guaranteed until thm 4.2 has been proved

• p203 thm 4.1 part d, where is says cv=0 the 0 should be bold

• p277 eg2 B' is NOT as basis

• p279 line 4 u_1->u_n

• p285 in proof of Thm5.5: 5times c_1m->c_m1; 3times c_n1->c_1n; 5times c_nm->c_mn;

• p496 answer #9(g) 2.1 : Should be “does not exist”

• p497 answer #3(e) 2.3: Should be “4x3”

• p498 answer #21 2.3: Should add also “BA=[-6+24i     5-20i ... 14+13i   23-26i]”

• p505 answer #18 3.3: Should be “|A-lambda I|” not “|A-lambda|”

• p530 answer #12 AppA: Should end with  “cu cross v”    not   “cu dot v”
