Let A$=[1004][1301][2001][0110][0110][1005][0110]$A$=[100-4][1-301][2001][0110][0110][1005][0110]$

Compute the area scaling factor of AAasf$($AA$)=$

Compute the sign of AA

If asf$($AA$)=0,$ you do not need to determine the sign of AA and can instead write sgn$($AA$)=0.$ Otherwise, if sgn$($AA$)$ is positive write $1$ or negative write $-1.$sgn$($AA$)=$

Compute the determinant of AAdet$($AA$)=$
