1.26*3.7+12.6*0.62+0.126 脱式简便计算
问题描述：
1.26*3.7+12.6*0.62+0.126 脱式简便计算
答
1.26*3.7+12.6*0.62+0.126
=1.26*3.7+12.6*6.2+1.26
=1.26*(3.7+6.2)
=1.26*9.9
=1.26*(10-0.1)
=1.26*10-1.26*0.1
=12.6-0.126
=12.474这是分布?还是2个答案,还有更简便的嘛一个答案，对了，还想问你是0.62*0.126还是0.63*0.1261.26*3.7+12.6*0.62+0.126 简便计算，我急要1.26*3.7+12.6*0.62+0.126 =12.6*0.37+12.6*0.62+12.6*0.01=12.6*（0.37+0.62+0.01）=12.6*1=12.6这是最简单的
