Section A.1 says:

   Let IntDiv(a,b) denote the integer division algorithm that takes
|  input integers a, b where a >= b >= 1 and returns integers (q,r)
|
   the quotient and remainder, respectively, of the division of a by b.
   (Thus, a = bq + r and 0 <= r < b.)

It should say:

   Let IntDiv(a,b) denote the integer division algorithm that takes
|  input integers a, b where  b >= 1  and returns integers (q,r), the
   quotient and remainder, respectively, of the division of a by b.
   (Thus, a = bq + r and 0 <= r < b.)

Notes:

inappropriate restriction specified + formatting flaw.

On page 17, Appendix A.1:
The restriction "a >= b" is not necessary and in fact inappropriate; the additional blank line seems to be an artifact of the editing process. Thus, the above text should better read [as above].
