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.

Are we (China's citizens) good or no good (in terms of character)? If you feel that we are good, key in $1$. Otherwise, key in $2$.

Not really a maths question...

@Stanley Guo Please encourage your students to submit their solution along with their problem. Often, I am unable to understand what they are trying to say.

Of the recent problems that they posted, 4 out of 6 of them are nonsensical, and I will want to delete them. They are number of triangles in this painting, $\sqrt{a} ^ 2$ has 3 possible answers, Subtract all the answers, Find the angle with answer of yes.

Please follow your students so that you will be able to see all of the problems that they have posted, and help to give them guidance about their problems.

Thanks for your cooperation.

Out of the 4 questions listed above, I have deleted 2 of them. They are

It is not clear which triangles are referred to in the diagram.

Answer of Yes / No did not make sense given the prompt of "Find the angle".
