如果有開方：把9開了

8*3*(11-10)=24

(8*3)*(11-10)=24

8*3/(11-10)=24

(8*3)/(11-10)=24

8*(11-10)*3=24

8/(11-10)*3=24

3*8*(11-10)=24

(3*8)*(11-10)=24

3*8/(11-10)=24

(3*8)/(11-10)=24

3*(11-10)*8=24

3/(11-10)*8=24

(11-10)*8*3=24

(11-10)*(8*3)=24

(11-10)*3*8=24

(11-10)*(3*8)=24

把八開三方：

2*(10-9+11)=24

(2+10)*(11-9)=24

2*(10+11-9)=24

2*(11-9+10)=24

2*(11+10-9)=24

(10+2)*(11-9)=24

(10-9+11)*2=24

(10+11-9)*2=24

(11-9)*(2+10)=24

(11-9+10)*2=24

(11-9)*(10+2)=24

(11+10-9)*2=24
