用3,8,12,13写出一种算式使结果是24每个数只能用一次

Answer 1

12*((13+3)/8)
(12*(13+3))/8
12*((13-8)-3)
12*(13-(8+3))
12*((3+13)/8)
(12*(3+13))/8
12/(8/(13+3))
(12/8)*(13+3)
12/(8/(3+13))
(12/8)*(3+13)
((13-12)*3)*8
(13-12)*(3*8)
((13-12)*8)*3
(13-12)*(8*3)
((13+3)*12)/8
(13+3)*(12/8)
((13-3)-8)*12
(13-(3+8))*12
(13+3)/(8/12)
((13+3)/8)*12
((13-8)-3)*12
(13-(8+3))*12
((3+13)*12)/8
(3+13)*(12/8)
3/((13-12)/8)
(3/(13-12))*8
3*((13-12)*8)
(3*(13-12))*8
(3+13)/(8/12)
((3+13)/8)*12
3*(8/(13-12))
(3*8)/(13-12)
3*(8*(13-12))
(3*8)*(13-12)
8/((13-12)/3)
(8/(13-12))*3
8*((13-12)*3)
(8*(13-12))*3
8*(3/(13-12))
(8*3)/(13-12)
8*(3*(13-12))
(8*3)*(13-12)

Answer 2

3×8×(13-12)=24

Answer 3

（13-3-8）*12=24

Answer 4

(13-3-8)ⅹ12=24
