Version: 3.3 (using KDE KDE 3.3.1) Installed from: Compiled From Sources Compiler: gcc 3.2.2 mandrake 9.1 OS: Linux This is not a crash bug, but when playing with kbruch, I got the following question: 1/5 - 5/2 i entered for a result in the top entry box "-23" and the bottom "10" (-23/10). The program said it is "correct" and displayed: 1/5-5/2 = -23/10 (what was displayed so far) = -23/10 = -2 * (3/10) of course, that -23/10 would be equal to -2 * (3/10) is very wrong! that would really be very confusing for a child who assumes the program is always right to see that... please see a screenshot at: http://www.chez.com/powerpeanuts/kbruch-bug.jpg
Created attachment 8022 [details] picture of the error the link i gave checked the referrer it seems, giving sometimes a 403. and an attachment is more permanent.
This is not a bug. The notation means -2 + (3/10). This is a common notation in some countries. The notation is described in the handbook.
as you wish.. however i would recommend to make it more explicit because at least in france what this means is definitely and unambiguously a multiplication. and possible confusion is the last thing you want when it comes teaching.

The problem is, that pupils who know this expression will not recognise it, if I write something like: 2 + 1/10 Maybe there is no way to do it correct for everybody. That's why I documented it in the handbook. Sebastian
I understand. maybe consider a combobox option "fraction display type" "compact" or "expanded" or something, and document it. best would probably be to ask the user at first application startup (alternative is the locale but it will take a long time to collect the whole list, and it's good if user can override it). i'm just saying, many people probably can't use the app as it is, and it's too bad.
