  3. 27 Card Trick. 1 volunteer needed!

  4. Explanation • 27 different situations. • W.L.O.G, we assume the card is the a th card, counting from top to bottom. • The card must be the [a/3] th card of the (a mod 3) pile. • [x] means the minimal integer lager than x.

  5. Explanation Put in middle. • After the 1st round, a th->b th. +9 • After the 2nd round, b th->c th. Put in bottom. +9 +9 • …

  6. Explanation • Middle, bottom, middle. 3^3=27,so this equals to 1. • Bottom, top, bottom.

  7. Explanation • Ternary(三进制). 0 stands for top, 1 stands for middle and 2 stands for bottom. It should be read in reverse (eg. 221 means middle, bottom, bottom).

  8. Talking jokers. 2 volunteers needed!

  9. Explanation First we should remember the number : x & y x th Joker 1 m Joker 2 y th n 0<x<18,18<y<36

  10. Explanation m m th card, you guys have seen what is the number and the patterm of it n m+n th card, you guys have seen what is the number and the patterm of it

  11. Explanation After we put them together, what can you find out ? Joker 2 n y-m th Joker 1 m x+n th

  12. Explanation counting the number of y-m and x+n + we have already knew the number of x and y =the number of m and n

  13. Explanation Counting the cards & find out the m+n th and n th card Joker 2 n n th Joker 1 m m+n th

  14. Explanation Just an arithmetical thing!
