6/2(2+1) 咁寫其實唔算 standard 吧?

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

6 / (2 (2+1) ) 就無異議鳥

用 Reverse polish notation

或 prefix notation

(* (/ 6 2) (+ 2 1))

點解會覺得 6/2(2+1) 唔一樣,係因為

當左 6/(2*(2+1)) ???

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

prefix notation 是有好處的,所以 LISP 先會用。
