2,3,5,11算24点两种方法

2-((3-5)*11) (2-5)*(3-11) 2+((5-3)*11) ((2*5)+3)+11 (2*5)+(3+11) (2-(5-11))*3 ((2-5)+11)*3 ((2*5)+11)+3

(2*(11-5))+12 ((11-5)*2)+12 12-(2*(5-11)) 12+(2*(11-5)) 12-((5-11)*2) 12/((11/2)-5) 12+((11-5)*2) ----END----

﹙5-11﹚×﹙3-7﹚ =(-6)x(-4) =24; ﹙7-3﹚×﹙11-5﹚ =4x6 =24; ﹙7×11-5)÷3 =(77-5)÷3 =72÷3 =24; ……

此题无解,因为无论如何计算都凑不出24这个数字。 除非将13改成14,则(3+5)*(14-11)=24成立。

其实根据列举法,一共有36种情况,而234101112只占其中的1/3,就是设定一个骰子的点数分别为123456在变化另一个骰子的点数,一共36种情况,再找出234101112的情况一共12种,在比较就是1/3小白胜率,2/3小米胜率

3×[﹙3×3﹚-1] ﹙3+3﹚×﹙3+1﹚ ﹙3+3﹚×﹙1+3﹚ ﹙1+3﹚×﹙3+3﹚ ﹙3+1﹚×﹙3+3﹚ [﹙3×3﹚-1]×3

(3-7)*(-11--5)=24 (-5-(7*-11))/3=24 (-5--11)*(7-3)=24 (-5-(-11*7))/3=24 (7-3)*(-5--11)=24 (-11--5)*(3-7)=24

((3*11)+2)-11 (3*11)+(2-11) (3*11)-(11-2) ((3*11)-11)+2 ((3*11)+2)-11 (3*11)+(2-11) (3*11)-(11-2) ((3*11)-11)+2 2+((3*11)-11) (2+(3*11))-11 2+((3*11)-11) (2+(3*11))-11 2-(11-(3*11)) (2-11)+(3*11) 2+((11*3)-11) (2+(11*3))-11 2-(...
