Coordinates of square vertices

The ABCD square has the center S [−3, −2] and the vertex A [1, −3]. Find the coordinates of the other vertices of the square.

Correct result:

x1 =  -7
y1 =  -1
x2 =  -2
y2 =  2
x3 =  -4
y3 =  -6

Solution:

s0=3 s1=2  x0=1 y0=3  d0=x0s0=1(3)=4 d1=y0s1=(3)(2)=1  nd n=d n.d=0  n0=d1=(1)=1 n1=d0=4  x1=s0d0=(3)4=7
y1=s1d1=(2)(1)=1
x2=s0+n0=(3)+1=2
y2=s1+n1=(2)+4=2
x3=s0n0=(3)1=4
y3=s1n1=(2)4=6
