(25+250)×4 =25×4+250×4 =100+1000 =1100

解: 25×50+250×5 =25×50+25×50 =25*(50+50) =25*100 =2500

25*210-250=25*(210-10)=25*200=5000

25×420+250×58简便方法 =25×(420+580) =25×1000 =25000

原式 =25x340+25x10x66 =25x340+25x660 =25x(340+660) =25x1000 =25000 或者 =25x10x34+250x66 =250x34+250x66 =250x(34+66) =250x100 =25000

(250-25)×8 =250×8-25×8 =2000-200 =1800

(250十100)÷25 =250÷25+100÷25 =10+4 =14 朋友,请采纳正确答案,你们只提问,不采纳正确答案,回答都没有劲!!! 朋友,请【采纳答案】,您的采纳是我答题的动力,如果没有明白,请追问。谢谢。
