	\problem{}
	Suppose $A$ is a real, square matrix that satisfies $A^3 = A + I$. \par
	Show that $\text{det}(A)$ is positive.

	\vfill

	\problem{}
	Suppose $A, B$ are $2 \times 2$ complex matrices satisfying $AB = BA$, \par
	and assume $A$ is not of the form $aI$ for some complex $a$. \par
	Show that $B = xA + yI$ for complex $x$ and $y$.

	\vfill

	\problem{}
	Is there an infinite sequence of real numbers $a_1, a_2, ...$ so that \par
	$a_1^m + a_2^m + ... = m$ for every positive integer $m$?
