Mistake
- (i) The expression $a_{i1} A_{i1} + a_{i2} + \cdots + a_{in} A_{in}$ has the same value for any $i$, and is the definition of $\det \mathbf A$, the determinant of $\mathbf A$.
Correction
The expression should read:
- $a_{i1} A_{i1} + a_{i2} A_{i2} + \cdots + a_{in} A_{in}$
In the $6$th edition, this section has been removed.
