负3,4,5,负9算24点

负3,4,5,负9算24点 (-3)(-9+5-4) =(-3)(-8) =24.

4*(-9-(5*-3)) 4*(-9-(-3*5)) (5-(4--9))*-3 ((5-4)+-9)*-3 ((5+-9)-4)*-3 (5+(-9-4))*-3 -3*(5-(4--9)) -3*((5-4)+-9) -3*((5+-9)-4) -3*(5+(-9-4)) -3*(-9-(4-5)) -3*((-9-4)+5) -3*((-9+5)-4) -3*(-9+(5-4)) (-9-(4-5))*-3 ((-9-4)+5)*-3 ((-...

3X(9-5+4) =3X8 =24

5-4=1 -9+1=-8 -8x-3=24

3×(9-4)+9 =3×5+9 =15+9 =24 4÷[3÷(9+9)] =4÷[3÷18] =4÷1/6 =24 4×9-3-9 =36-3-9 =33-9 =24

(9-5)×(3+3)请点赞

(9-5)x(3+3)=24

(3-1)*(8-(-4))=24 (3-1-8)*-4=24 8-(3+1)*-4=24 ============================= 9-(-4)-(-5)-(-6)=24

-5乘以-9等于45。3×7等于21。45-21等于24。

解法如下,点拨:15+9=24 1.3×5+9=24
