24点的题目:“5,9,7,2”四个数用加减乘除凑24
1,-2,5,-7,将这四个数进行加减乘除算24点
有负2,4,负5,负10四个数 用加减乘除算24点
:用2 5 8 10四个数通过加减乘除算24点,可列式为( )
2,-3,-4,5这四个数用加减乘除怎么组成24点?
四个数:-6、-9、2、7 加减乘除结果为24
三个24点的题目一. 3,4,—6,10四个数,用加减乘除四则运算计算出24;(1)__________________
按"24点"的游戏规律(每个数用且只用一次加减乘除四则运算),现有四个数3,-5,2,-13
5、请分别用3477和3377四个数算24点(加减乘除)
用加减乘除把四个数组成24:
算24点根据24点算法现有四个数-2,4,-5,-10,每个数只用一次用加减乘除使其结果等于24
24点:利用加减乘除括号使四个数4,1,5,6等于24.注意不能改变数的顺序.
