(1)5.7-4.2-8.4-2.3+1又5分之一要用简便方法
5.7减4.2减8.4减2.3加1又5分之1
有理数的减法中-4.2+5.7-8.4-2.3=什么
-4.2+5.7-8.4+10
-4.2+5.7-8.4.10
-4.2+5.7-8.4+10
-4.2+5.7-8.4+10.2
-4.2+5.7-8.4+10
-4.2+5.7-8.4+10
-4.2+5.7-8.4+10;计算
-4.2+5.7-8.4+10=?
-4.2+5.7-8.4+10=
像(-5)+(-9)-(+3)-(-7)还有-4.2+5.7-8.4-2.3有解题方法.一定要有解题方法(也就是概念.)
-4.2+5.7-8.4+10简便计算
负4.2+5.7减8.4+10
—4.2+5.7—8.4+10
-8.4+10-4.2+5.7=
