{{{z[1]=-23+7i}}}
{{{z[2]=4+11i}}}
{{{z[3]=-4-12i}}}


{{{z=(z[1]*z[2]*z[3])/(z[1]+z[2])}}}


{{{z=((-23+7i)*(4+11i)*(-4-12i))/((-23+7i)+(4+11i))}}}


{{{z=((-92-253i+28i+77i^2)*(-4-12i))/(-23+7i+4+11i)}}}


{{{z=((-92-253i+28i+77(-1))*(-4-12i))/(-23+7i+4+11i)}}}


{{{z=((-92-253i+28i-77)*(-4-12i))/(-23+7i+4+11i)}}}


{{{z=((-169-225i)*(-4-12i))/(-19+18i)}}}


{{{z=(676+2028i+900i+2700i^2)/(-19+18i)}}}


{{{z=(676+2928i+2700(-1))/(-19+18i)}}}


{{{z=(676+2928i-2700)/(-19+18i)}}}


{{{z=(-2024+2928i)/(18i-19)}}}


{{{z=((-2024+2928i)(18i+19))/((18i-19)(18i+19))}}}


{{{z=(-91160+19200i)/((18i)^2-19^2)}}}


{{{z=(-91160+19200i)/(324i^2-361)}}}


{{{z=(-91160+19200i)/(324(-1)-361)}}}


{{{z=(-91160+19200i)/(-324-361)}}}


{{{z=(-91160+19200i)/(-685)}}}


{{{z=-91160/(-685)+19200i/(-685)}}} ..divide by {{{5}}}


{{{z=18232/137-3840i/137}}}
