通式可以吗?任意四个常数代人下面式子都可以得到24 ((A')!+(B')!+(C')!+(D')!)!=24 比如这道题: ((11')!+(11')!+(2')!+(2')!)! =(0!+0!+0!+0!)! =(1+1+1+1)! =4! =24
1: 11 × (2 + 2 ÷ 11) 2: 11 × (2 + (2 ÷ 11)) 3: 11 × (2 ÷ 11 + 2) 4: 11 × ((2 ÷ 11) + 2) 5: (2 ÷ 11 + 2) × 11 6: ((2 ÷ 11) + 2) × 11 7: (2 + 2 ÷ 11) × 11 8: (2 + (2 ÷ 11)) × 11
