确定(268✖️870)✖️30简便计算?
还是(268十870)✖️30简便计算?
是第一个
(268✖️870)✖️30=268x(870x30)=268x26100=(300-32)x26100=300x26100-32x26100=7830000-(30+2)x26100=7830000-30x26100-2x26100=7830000-783000-522=7046478
(268✖️870)✖️30=268x(870x30)=268x26100=(300-32)x26100=300x26100-32x26100=7830000-(30+2)x26100=7830000-30x26100-2x26100=7830000-783000-52200=649800
最后一段是正确答案
总之正确答案是(268✖️870)✖️30=268x(870x30)=268x26100=(300-32)x26100=300x26100-32x26100=7830000-(30+2)x26100=7830000-30x26100-2x26100=7830000-783000-52200=649800
不好意思订正一下正确答案是总之正确答案是(268✖️870)✖️30=268x(870x30)=268x26100=(300-32)x26100=300x26100-32x26100=7830000-(30+2)x26100=7830000-30x26100-2x26100=7830000-783000-52200=6994800
