one method is to have:L 9 8 7 6 5 9 8 7 6 5 maps to

then e.g. forCT^s~6 ¥Ò¤l¤A¤¡, add them together, gets 9+8+9+8 = 34.X+ divided by 5, remainder is 4, and then, I forgot ... but it's documented in many books./4a~ ©½t¥Í³N¼Æ¬ã¨sªÀ -- ³N¼Æ¬ã¨s¡@¡@ n)bU the 2nd method is based on previous method, and using the "palm" to aid the calculation, and should be able to count the result within 2-5 seconds. It's quite hard for me to illustrate here though ... it's maths, anyway. not hard to derive oneself. This method is documented in 1 or 2 books only -- the books I have read so far.*y3GDD ©½t¥Í³N¼Æ¬ã¨sªÀ -- ³N¼Æ¬ã¨s¡@¡@ (jyw But I have to admit that if you have good memory, ¤èªk¤@ is a good way.IN} ©½t¥Í³N¼Æ¬ã¨sªÀ -- ³N¼Æ¬ã¨s¡@¡@ seD And finally, my suggestion is, to prepare a cheat-sheet ... or, save it in PDA...Ni~^5g
