下面每條算式都有四個「5」,不過全部的運算附號都不見了。你能填上 +、- 、x、/ 和 ( ) ,得出答案1至6嗎?
1=5 5 5 5
2=5 5 5 5
3=5 5 5 5
4=5 5 5 5
5=5 5 5 5
6=5 5 5 5

1=(5+5)/(5+5)
2=5/5+5/5
3=5-(5+5)/5
4=(5X5-5)/5
5=(5-5)X5+5
6=(5X5+5)/5

俾阿潘生快我一步潻,我既答案差唔多︰
1=5/5-5+5 (5+5-5)/5 5/(5+5-5) ((5x5)/5)/5 (5+5)/(5+5) (5/5)/(5/5) (5x5)/(5x5).......
2=5/5+5/5
3=(5+5+5)/5
4=(5x5-5)/5
5=(5-5)x5+5
6=(5x5+5)/5
