Question

用1，3，5，9算24点，怎样算最后一步是和乘9

Answer 1

最后一步不能乘9,是（9-3）x（3+1）=24

Answer 2

((5*3)+9)/1
(5*3)+(9/1)
((5*3)+9)*1
(5*3)+(9*1)
((5/3)+1)*9
(5*3)+(1*9)
((5*3)/1)+9
(5*(3/1))+9
((5*3)*1)+9
(5*(3*1))+9
(5-1)*(9-3)
(5/(1/3))+9
((5/1)*3)+9
((5*1)*3)+9
(5*(1*3))+9
9+((5*3)/1)
(9+(5*3))/1
9+(5*(3/1))
9+((5*3)*1)
(9+(5*3))*1
9+(5*(3*1))
9*((5/3)+1)
9+(5/(1/3))
9+((5/1)*3)
9+((5*1)*3)
9+(5*(1*3))
(9-3)*(5-1)
9+((3*5)/1)
(9+(3*5))/1
9+(3*(5/1))
9+((3*5)*1)
(9+(3*5))*1
9+(3*(5*1))
9+(3/(1/5))
9+((3/1)*5)
9+((3*1)*5)
9+(3*(1*5))
9+((1*5)*3)
9+(1*(5*3))
(9/1)+(5*3)
9*(1+(5/3))
(9*1)+(5*3)
9+((1*3)*5)
