Question about the Dirac notation for partial trace

Are there non-commuting matrices for which $\mathrm{tr}(ABC)=\mathrm{tr}(BAC)$?

What is the intuition behind the trace of an endomorphism?

If $A^3 = I_n$ then $\operatorname{tr}(A)\in\Bbb Z$

$\det(I+A)=1+\operatorname{Tr}(A)$ if $\operatorname{rank}(A)=1$

An $n\times n$ matrix that has exactly one $1$ and one $-1$ in each row and column and others are $0$

When $A$ is $3\times3$, prove that $A^2=0$ iff $A$ has rank less than or equal one and trace zero

When does $\mbox{tr} \left( A^2 \right) = \mbox{tr} (A)^2$ hold?

Prove that $A^5 \neq I$
