5个5怎么就等于4

(4÷4)*(4÷4)+4=5 希望能帮上您,如尚且满意敬请采纳,o(∩_∩)o谢谢~~

5/5=1 1/5=1/5 5-1/5=4/5 5*4/5=4 5*(5-(5/5)/5)=4

5-(5/5)+(5-5)=4

4种运算各用1次,所以任何2个5之间都必须填上1个运算符,不会出现55,555的情况. 按照实际计算的顺序,【相当于计算机计算时的顺序,也就是去掉括号后的计算顺序】,4个运算符只有4!= 4*3*2*1 = 24种. 因此, 5个5加减乘除各用1次,

5*5-5再除以5 不就是4????

5-(5÷5)x(5÷5)=4 5x5/5-5÷5=4 5+5+5+5)÷5 =4

5-(5+5)/(5+5)=45-1=4,4个5带括号运算等于1,不能只用乘除,如5/5*5/5=1等,需要用加法算式的乘除,(5+5)/(5+5)=1符合.

(5*5-5)÷5=4 (*^__^*) 嘻嘻……

5+5-5-5*5 *是除以 此回答不需要括号 先乘除后加减 结果也是4

下面列出这24种情形,5+5 = 10, 10 - 5 = 5, 5*5 = 25, 25/5 = 5 [+-*/]5+5 = 10, 10 - 5 = 5, 5/5 = 1, 1*5 = 5 [+-/*]5+5 = 10, 10*5 = 50, 50-5 = 45, 45/5 = 9 [+*-/]5+5 = 10, 10*5 = 50, 50/5 = 10, 10-5 = 5 [+*/-]5+5 = 10, 10/5 = 2, 2-5 = -8, -8*5 = -40 [+/-*]5+5
