-1 -1 v v sqrt(v ) 16 11 ***9 29 29 ***8
***How are these square roots? 9 is certainly not the square root of 11, nor is 8 the square root of 29, even modulo 35.
Bzzt! Try Again. If you use bc, you will notice that 9^2 mod 35 == 11 and 8^2 mod 35 == 29... You should go take your number theory class!

mean "the inverse of v." Are these two expressions interchangeable or is this something that I should have found in the errata?
Yes. It is the multiplicative inverse. This is very basic math. Go re-read your 7th-grade algebra book: v^(-1) == 1/v Take your number theory class, and if you can't figure out after that, re-ask the questions. -derek
