As I recall, some students at an afternoon "Talmud Torah" class in the Yonkers of my youth (1960's) were being told to do this. But I never heard of a regular kametz being used for a minus sign.

The lack of use of a minus sign to make it less obvious.<br />Another possibility might be that at some time Jews were only allowed to print Hebrew books and using a non-hebrew symbol may have upset some guild.<br /><br />MidwestAnonymousnoreply@blogger.com
