原文是:

三人同行七十里,
五树梅花二一枝,
七子团圆正半月,
除百零五便得知!

The one with "21 people riding 5 horses" is the one that rang a bell to me. I must have heard it before my St B days.

And BTW, happy birthay Wongyan, and try to explain to your kid why it's was not too unusual to have 3 kids having the same birthday in a class of 40 pupils.

And nice avatar!

Finally find a suitable web page to copy/paste the symbols like: ∴, ∠,  △. 

Oh btw, I've updated the proof above.

My daughter is going to Brunei today for the Southeast Asia Math Competition. She's part of the 6-member team from her school. Some of the example questions below. The questions are not too hard, but you have to answer very fast.

Anyway, I was talking to Nelson about some other "talented kids" program. One such program is the EPGY from Stanford. I looked at the questions in the application form, and some of them I don't even know how to start...  ???

It's not mandatory to answer any question in the application form, and they say clearly that they don't expect you to answer all. I will post a copy here later.
