Monument to the Victims of Jewish Ghetto

This geocache is located at the Monument to the Victims of the Jewish Ghetto in Chisinau. Please take your time when visiting this site. At the entrance to the small park there is a sign giving you a few information about the ghetto. If you would like to have some further readings, I recommend to visit the webpage of the Jewish Memory in Moldova. 

To find the final coordinates you need to read the sign. Find out the sad numbers of the ghetto's residents reported by General Constantin Nicolescu. 

The number of imprisoned women minus the number of imprisoned children equals A.

The number of imprisoned men equals B.

The final coordinates are at: 

N 47° A + 196

E 028° B x 12 + 689

Make sure to follow the rules of common math.
