过程: 4×(7÷7+5)=24 5×7-4-7=24

4x[7-(5÷5)]=24

13, 5, 7, 4的24点答案: 1: (13 - 5) × (7 - 4) 2: (13 × 7 + 5) ÷ 4 3: ((13 × 7) + 5) ÷ 4 4: (5 + 13 × 7) ÷ 4 5: (5 + (13 × 7)) ÷ 4 6: (5 - 13) × (4 - 7) 7: (5 + 7 × 13) ÷ 4 8: (5 + (7 × 13)) ÷ 4 9: (7 × 13 + 5) ÷ 4 10: ((7 × 13)...

1: 4 - (5 - 7) × 10 2: 4 - ((5 - 7) × 10) 3: 4 + (7 - 5) × 10 4: 4 + ((7 - 5) × 10) 5: 4 - (10 × (5 - 7)) 6: 4 - 10 ×(5 - 7) 7: 4 + (10 × (7 - 5)) 8: 4 + 10 ×(7 - 5) 9: (7 - 5) × 10 + 4 10: ((7 - 5) × 10) + 4 11: (10 × (7 - 5))...

(4-7)*(5-13) (5+(7*13))/4 (5-13)*(4-7) (5+(13*7))/4 (7-4)*(13-5) ((7*13)+5)/4 (13-5)*(7-4) ((13*7)+5)/4

3*(5-(4-7)) 3*((5-4)+7) (3+5)*(7-4) 3*((5+7)-4) 3*(5+(7-4)) ((3*4)+5)+7 (3*4)+(5+7) ((3*4)+7)+5 (3*4)+(7+5) 3*(4*(7-5)) (3*4)*(7-5) 3*((7-5)*4) (3*(7-5))*4 3*((7+5)-4) 3*(7+(5-4)) 3*(7-(4-5)) 3*((7-4)+5) 5+((3*4)+7) (5+(3*4))+7...

1: (7 - 5) × 10 + 4 2: ((7 - 5) × 10) + 4 3: (10 × (7 - 5)) + 4 4: 10 × (7 - 5) + 4 5: 4 + (7 - 5) × 10 6: 4 + ((7 - 5) × 10) 7: 4 - (5 - 7) × 10 8: 4 - ((5 - 7) × 10) 9: 4 + (10 × (7 - 5)) 10: 4 + 10 ×(7 - 5) 11: 4 - (10 × (5 ...
