The other problem:
<math>\begin{pmatrix}
2 & 0 & 0 \\
0 & 2 & 0 \\
0 & 0 & 2 \\
\end{pmatrix}</math>
*Eigenvalues: 2
*Determinant: 8
The ''algebraic multiplicity'' has to be taken into account, the simple sentence ''the determinant is equal to the product of the eigenvalues of a matrix'' was misleading.
