用3.3.7.7算二十四点
用3.3.7.7算二十四点
3除以7等于7分之3
7分之3加上3等于7分之24
7分之24乘以7等于24
算式如下:
(3÷7+3)×7=24
3.3.7.7求出二十四点和2.6.7.8.求出二十四点算式
7÷(3+3/7)=24 (2+7-6)*8=24
算二十四点
只用加减乘除是算不出来的,理由只能是列举
(1)若计算过程中,运用了加法,那么有7+7=14,或7+3=10,或7+5=12,或3+5=8,可是3个数就比较显然了,无论14,3,5;10,7,5,12,3,7,还是8,7,7,都算不出24
(2)还有讨论如果存在减法,这类似,我就不说明了
(3)如果没有加减法就只有乘除法了,那7是一个质数,且不是24因数,所以必须除掉,7/7=1,剩下3和5根本算不出24.
1.(-6+10+4)3 2.3(10-4)-(-6) 3.4-10(-6)除以3
(0!+0!+0!+0!)=24
(9-2*3)*8=24
(7 + (4 ÷ 4)) × 3=24 (7 + 4 ÷ 4) × 3=24
(1) (5 - 2 + 3) × 4或 (4 + 3 + 5) × 2
(2)(2 - 3 + 7) × 4或2 × (7 + 3) + 4或(2 + 4) × (7 - 3)
(3) (2 × 7 - 6) × 3或 3 + (6 ÷ 2) × 7或(6 ÷ 2) + 3 × 7
(4)(4 - 2) × (5 + 7)或4 ÷ 2 ×(7 + 5)
(5)2 × 6 + 5 + 7或2 × 6 ×(7 - 5)
(6)(3 - 4 + 5) × 6
(7)3 × 4 + 5 + 7
(8)3.4.6.7无答案
(9)(5 - 6 + 7) × 4
(10)(5 + 7) ÷ 3 × 6
(11)4 + 2 × 7 + 6
很全了~~~~
