奥数题填入运算符号使算式成立
1/2 1/2 1/2 1/2 =1
1/2 1/2 1/2 1/2 =2
1/2 1/2 1/2 1/2 =3
1/2 1/2 1/2 1/2 =4
填入运算符号使算式成立
答
1/2÷1/2×1/2÷1/2=1
1/2÷1/2+1/2÷1/2=2
(1/2+1/2+1/2)÷1/2=3
1/2÷1/2÷1/2÷1/2=4
答
0.5+0.5-0.5+0.5=1
0.5+0.5+0.5+0.5=2
(0.5+0.5+0.5)/0.5=3
(0.5+0.5)/(0.5*0.5)=4
答
1/2+1/2+1/2-1/2 =1
1/2+1/2+1/2+1/2 =2
(1/2+1/2+1/2)/(1/2)=3
(1/2)/[(1/2)*(1/2)*(1/2)]=4
