小学四年级加减乘除竖式各10道

小学四年级加法竖式计算829+256

解题思路:两个加数的个位对齐,再分别在相同计数单位上的数相加,相加结果满10则向高位进1,高位相加需要累加低位进1的结果。

解题过程:

步骤一:9+6=5 向高位进1

步骤二:2+5+1=8

步骤三:8+2=0 向高位进1

根据以上计算步骤组合计算结果为1085

验算:1085-256=829

扩展资料-验算结果:将减数与被减数个位对齐,再分别与对应计数单位上的数相减,不够减的需向高位借1,依次计算可以得出结果,减数小于被减数将两数调换相减最后结果加个负号;小数部分相减可参照整数相减步骤;

解题过程:

步骤一:15-6=9 向高位借1

步骤二:8-5-1=2

步骤三:10-2=8 向高位借1

步骤四:1-0-1=0

根据以上计算步骤组合计算结果为829
