负3,负5,0,正3,正4中选四个数算24点?

(-3-5)*(0-3)=24

(5-2+3)x4=24

1、常规运算: 3*6+1*4 3*6*1+4 (3*6+4)*1 (3*6+4)/1 6/(1-3/4) 2、特殊运算: 4*6±3mod1 4!+6*(3mod1) 4!*(6/3-1) 4*6*1^3

用3,3,5,7算24点,共有4种算法。 [﹙5×3﹚-7]×3 3×[﹙3×5﹚-7] 3×[﹙5×3﹚-7] [﹙3×5﹚-7]×3

6*(9-5)*1 (5-1)*(9-3) (3+5)*(9-6) (9÷3+1)*6

2*5+3*4

((-5+3)*-3)*4 (-5+3)*(-3*4) ((-5+3)*4)*-3 (-5+3)*(4*-3) ((-5-4)*-3)-3 ((-3--5)*3)*4 (-3--5)*(3*4) -3*((-5+3)*4) (-3*(-5+3))*4 -3-((-5-4)*3) ((-3--5)*4)*3 (-3--5)*(4*3) (-3*(-5-4))-3 -3-(3*(-5-4)) -3*((3+-5)*4) (-3*(3+-5))*4 -3+...

3*(10+2)-12 =3*12-12 =36-12 =24; 3*(10*2-12) =3*(20-12) =3*8 =24; 3*10-12/2 =30-6 =24; 3*12-10-2 =36-10-2 =24; 10/(3+2)*12 =10/5*12 =2*12 =24; (10*2-12)*3 =(20-12)*3 =8*3 =24; 10*2+12/3 =20+4 =24; …… 供参考。
