See the picture. I have clearly not solved the question, yet the system thinks I have.

Here is what is going on:
Some of the problems in the practice section are automatically generated from canonical types within that topic. In a previous set you had solved one that was essentially the same problem with different numbers, for extra practice. Our naive "solved by" box therefore tells you that you have already solved it.

Did you fix it?
Evidently not because it just happened to me again - except cross-technique. Presumably because it was a duplicate problem (literally word for word duplicate).
and again, with another canonical type.
hmmmm....interesting. We will look into it. Thanks.
This happened to me as well, just this week. The additional points didn't get counted though, so I thought it was just because of poor Internet connection. I didn't bother taking a screenshot or reporting the glitch, but if it keeps happening to different people...
I had the same thing happen to me.
Is this the first or second question of the problem set?
so what makes you think the system thinks you have solved it?
The sidebar says so in the image
I see. It seems like the sidebar is about the first problem of the set, so that's indeed a glitch. Does a refresh solve the problem? (not the math one ;-) )
