The Check OK computation proves that the proposed scalar multiplication is well-defined and does not contradict the defining relation of the quotient ring RR. It shows that the generator of the ideal, xy+yxxy+yx, acts as zero on every vector because the matrices XX and YY satisfy XY+YX=0XY+YX=0.

Conditions: R=C⟨x,y⟩/⟨xy+yx⟩R = \mathbb{C}\langle x,y\rangle / \langle xy+yx\rangle.; X,YX,Y solve XY+YX=0XY+YX=0.; The module action is defined by (x+I)v=Xv(x+I)v=Xv and (y+I)v=Yv(y+I)v=Yv.

The matrix equation enters at the final step of the verification computation, where the expression (XY+YX)v(XY+YX)v is evaluated. Because XX and YY are assumed to solve XY+YX=0XY+YX=0, this expression equals the zero vector, confirming that the ideal generator acts trivially.

Conditions: X,Y∈Mn×n(C)X,Y \in M_{n\times n}(\mathbb{C}).; XY+YX=0XY+YX=0.; The verification expands (xy+yx+I)v(xy+yx+I)v into (XY+YX)v(XY+YX)v.
