glitch

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

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

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?

Bob Krueger - 8 years ago

Evidently not because it just happened to me again - except cross-technique. Presumably because it was a duplicate problem (literally word for word duplicate).

Matthew Lipman - 8 years ago

@Matthew Lipman – and again, with another canonical type.

Matthew Lipman - 8 years ago

hmmmm....interesting. We will look into it. Thanks.

Peter Taylor Staff - 8 years ago

Is this the first or second question of the problem set?

Tim Vermeulen - 8 years ago

the second

Matthew Lipman - 8 years ago

so what makes you think the system thinks you have solved it?

Tim Vermeulen - 8 years ago

@Tim Vermeulen – The sidebar says so in the image

Matthew Lipman - 8 years ago

@Matthew Lipman – 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 ;-) )

Tim Vermeulen - 8 years ago

I had the same thing happen to me.

Bob Krueger - 8 years ago

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...

Okay..
