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 存疑请追问,满意请采纳
