1,2,3,4,5,6,7,8,9,10,11,12,13从中选4个数,组成24答:3*(13-2-3)=24 (9-3)+5+13=24 4*[12/(6-3)]=24 (8-4)*(9-3)=24 (7-3)*(8-2)=24 (13-3)+(4-2)=24 (12-6)*(5-1)=24 (11-5)*(1+3)=24 2+3+6+13=24 2+4+6+12=24 2+5+11+6=24 3+4+6+11=24 (13-1)*(4-2)=24 4...
3,4,5,8和2,3,4,6和8,10,12,8还有1,3,4,2怎么组成结果是24要对的答:3,4,5,8:(5-3)x(4+8)=24 2,3,4,6:4x6x(3-2)=24 8,10,12,8:(12-10)x8+8=24 1,3,4,2:3x1x(2x4)=24
