六年级脱式计算题能简算要减算50到左右带答案过程。 有100道脱式简便计算题带答案和过程吗
解题思路:四则运算规则(按顺序计算,先算乘除后算加减,有括号先算括号,有乘方先算乘方)即脱式运算(递等式计算)需在该原则前提下进行
解题过程:
82×27+27×28
=(82+28)×27
=110×27
=2970
扩展资料{竖式计算-计算过程}:先将两乘数末位对齐,然后分别使用第二个乘数,由末位起对每一位数依次乘上一个乘数,最后将所计算结果累加即为乘积,如果乘数为小数可先将其扩大相应的倍数,最后乘积在缩小相应的倍数；
解题过程:
步骤一:7×110=770
步骤二:2×110=2200
根据以上计算结果相加为2970

延展回答
脱式计算即递等式计算，把计算过程完整写出来的运算，也就是脱离横式的计算。
在计算混合运算时，通常是一步计算一个算式(逐步计算，等号不能写在原式上)，要写出每一步的过程。一般来说，等号要往前，不与第一行对齐。也就是离开原式计算。
(脱字念tuo)主要掌握的是记住要先算乘、除法，后算加、减法。在乘除法连续计算时中，要按从左往右的顺序依次计算。遇到括号，要首先计算括号内部。
在脱式过程中要按运算顺序划出运算顺序线，还要做到"三核对"，一要核对从书上把题抄到作业本上数字、符号是否抄对。二要核对从横式抄到草稿竖式的数字、符号是否抄对。三要核对把草稿竖式上的得数，抄到横式上是否抄对，小数点是否点对地方，有无遗漏。
