用4,10,7,5组成24点

(7-5)*10+4=24

(5+7)*(10/5)=12*2=24.

7*10/5+10=24

5加7

用加减乘除有两种算法:5*7-10-1=24(1+7÷5)*10=24

1: 4 - (8 - 10) * 102: 4 - ((8 - 10) * 10)3: 4 + (10 - 8) * 104: 4 + ((10 - 8) * 10)5: 4 - (10 * (8 - 10))6: 4 - 10 *(8 - 10)7: 4 + (10 * (10 - 8))8: 4 + 10 *(10 - 8)9: (4 - 10 ÷ 10) * 810: (4 - (10 ÷ 10)) * 811: 8 - 4 + 10 + 1012: (8 - 4) + 10 + 1013: (8 - 4 + 10) +

1: 10 * (2 + 4 ÷ 10)2: 10 * (2 + (4 ÷ 10))3: 10 * (4 ÷ 10 + 2)4: 10 * ((4 ÷ 10) + 2)5: (2 + 4 ÷ 10) * 106: (2 + (4 ÷ 10)) * 107: (4 ÷ 10 + 2) * 108: ((4 ÷ 10) + 2) * 10

1: (4 ÷ 4 + 7) * 3 2: ((4 ÷ 4) + 7) * 3 3: 4 * (3 - 4 + 7) 4: 4 * ((3 - 4) + 7) 5: 4 * (3 - (4 - 7)) 6: 4 * (3 + 7 - 4) 7: 4 * ((3 + 7) - 4) 8: 4 * (3 + (7 - 4)) 9: 4 * (7 - 4 + 3) 10: 4 * ((7 - 4) + 3) 11: 4 * (7 - (4 - 3)) 12: 4 * (7 + 3 - 4) 13: 4 * ((7 + 3) - 4) 14: 4 * (7 + (3 - 4))

1: 4 * (7 + 8 - 9)2: 4 * ((7 + 8) - 9)3: 4 * (7 + (8 - 9))4: 4 * (7 - 9 + 8)5: 4 * ((7 - 9) + 8)6: 4 * (7 - (9 - 8))7: 4 * (8 + 7 - 9)8: 4 * ((8 + 7) - 9)9: 4 * (8 + (7 - 9))10: (4 + 8) * (9 - 7)11: 4 * (8 - 9 + 7)12: 4 * ((8 - 9) + 7)13: 4 * (8 - (9 - 7))14: (7 + 8 - 9) * 415: ((7 +

本方法是应用在10以内任何任意4个数字组合,加减乘除得到24的计算方法具体的的游戏规则如下:一副牌中抽去大小王剩下52张,(如果初练也可只用1~10这40张牌)任意抽取4张牌(称牌组),用加、减、乘、除(可加括号)把牌面上的数
