1/2*(1/2 - 1/2 + 1/2 - 1/2)=01/2*(1/2 + 1/2 + 1/2 + 1/2)=1
(1/2 +1/2) * (1/2 / 1/2 /1/2)=2
(1/2 +1/2) + (1/2 / 1/2 /1/2)=3
(1/2 + 1/2 + 1/2 + 1/2) / 1/2=4
(1/2 + 1/2 + 1/2) /( 1/2 * 1/2)=6
如何等于5，交给其他高手
1/2*(1/2 - 1/2 + 1/2 - 1/2)=0
1/2*(1/2 + 1/2 + 1/2 + 1/2)=1
(1/2 +1/2) * (1/2 / 1/2 /1/2)=2
(1/2 +1/2) + (1/2 / 1/2 /1/2)=3
(1/2 + 1/2 + 1/2 + 1/2) / 1/2=4
(1/2 + 1/2 + 1/2) /( 1/2 * 1/2)=6
不可能等于5 你再好好看看题目
(1/2+1/2-1/2-1/2)*1/2=0 1/2 +1/2+(1/2-1/2))*1/2=1 (1/2 +1/2) /1/2+1/2-1/2=2 (1/2 +1/2) /1/2+1/2+1/2=3 (1/2+1/2+1/2+1/2)/1/2=4 (1/2+1/2) /1/2^2+1/2+1/2=5 1/2 / 1/2^2+1/2 / 1/2^2*1/2=6
1/2-1/2×1/2-1/2×1/2=0；1/2×1/2÷（1/2-1/2×1/2）=1；（1/2+1/2+1/2+1/2）÷1/2=2；
（1/2+1/2）÷1/2+1/2+1/2=3；（1/2+1/2+1/2+1/2）÷1/2=4；1/2 1/2 1/2 1/2 1/2=5；
（1/2+1/2）÷（1/2×1/2×1/2）=6；
