四个3利用加,减,乘,除号和括号使其分别等于1,2,3,4,5,6

问题描述:

四个3利用加,减,乘,除号和括号使其分别等于1,2,3,4,5,6

1: (3+3)/(3+3)
2: 3/3+3/3
3: 3*3-3-3
4: (3*3+3)/3
5: (3+3)-(3/3)
6: 3+3+3-3

答:
3÷3×3÷3=1,3×3÷3÷3=1
3÷3+3÷3=2,(3×3-3)÷3=2
3×(3-3)+3=3,3×3-3-3=3
(3+3×3)÷3=4
(3+3)÷3+3=5
3×3÷3+3=6,3+3+3-3=6

(3+3-3)/3=1
3/3+3/3=2
3*3-3-3=3
(3*3+3)/3=4
3+3-3/3=5
3+3+3-3=6
