在5个"1/2 "之间添上加号,减号,乘号,除号和括号等运算符号,使等式成立.今晚就要(1) 2/1 2/1 2/1 2/1 2/1=0(2) 2/1 2/1 2/1 2/1 2/1=1 (3) 2/1 2/1 2/1 2/1 2/1=2(4) 2/1 2/1 2/1 2/1 2/1=3(5) 2/1 2/1 2/1 2/1 2/1=
在5个"1/2 "之间添上加号,减号,乘号,除号和括号等运算符号,使等式成立.今晚就要
(1) 2/1 2/1 2/1 2/1 2/1=0
(2) 2/1 2/1 2/1 2/1 2/1=1
(3) 2/1 2/1 2/1 2/1 2/1=2
(4) 2/1 2/1 2/1 2/1 2/1=3
(5) 2/1 2/1 2/1 2/1 2/1=4
(6) 2/1 2/1 2/1 2/1 2/1=6
在这几个算式的“2/1”中间加上 加号,减号,乘号,除号和括号等运算符号,使等式成立.
是二分之一,好像打错了.sorry!

你这是二分之一还是一分之二啊

(0.5-0.5)* ()后边随便
(0.5+0.5+0.5+0.5)*0.5 = 1
(0.5+0.5) / 0.5 + 0.5-0.5 = 2
(0.5+0.5)/0.5 +0.5+0.5 =3
(0.5+0.5+0.5+0.5)/0.5=4
(0.5+0.5+0.5)/0.5/0.5 = 6
