話如果用 over 6/2(2+1) 答案唔一樣

6/2(2+1) 咁寫其實唔算 standard 吧?

無分別

睇錯,話以上嗰個"6/2(2+1)" 係想將條式寫成 6/ (2*3) = 1,呢個就不對

我意思係, 因為電腦打字關係先會寫成 6/2(2+1), 現實係會寫到好似 wolfram 咁, 無 ambiguity

jackyee u mean 6 / (2 (2+1) )?
陳電鋸
2011-05-06T04:47:42.000Z
6/2 * (2+1)
jackysee
2011-05-06T04:47:58.000Z
6 / (2 (2+1) ) 就無異議鳥
陳電鋸
2011-05-06T04:48:56.000Z
用 Reverse polish notation
陳電鋸
2011-05-06T04:50:00.000Z
或 prefix notation
陳電鋸
2011-05-06T04:50:41.000Z
(* (/ 6 2) (+ 2 1))
陳電鋸
2011-05-06T04:51:40.000Z
點解會覺得 6/2(2+1) 唔一樣,係因為
陳電鋸
2011-05-06T04:52:05.000Z
當左 6/(2*(2+1)) ???
jackysee
2011-05-06T04:53:53.000Z
應該係
jackysee
2011-05-06T04:54:27.000Z
但用番紙筆應該出 www4d.wolframalpha.com/C...

prefix notation 可以就咁讀出 the product of the quotient of 6 by 2 and the sum of 2 and 1

無賴講法: 先乘除後加減嘛, 所以乘>除
陳電鋸
2011-05-06T05:04:24.000Z
prefix notation 是有好處的,所以 LISP 先會用。
