Glitch When Dividing a Negative Number

Glitch When Dividing a Negative Number

There seems to be a problem dividing negative numbers. I just tried to divide
-350 by 7 (function=-350/7). The result was a dash "-". I then tried to divide +350 by 7 (function=350/7). I got the correct answer (50). Has anyone else run into this glitch when dividing negative numbers? Is there a workaround?
