111x999十333x667简便计算

333x667+111x999 = 333x667+111x3x333 = 333x(667+333) = 333x1000 =333000

999x111+333x667=999x111+667x3x111=(999+667x3)x111=3000x111=333000

9999*1111+333*667 =(10000-1)*1111+333*(1000-333) =11110000-1111+333000-333*333 =11110000-1111+333000-9*111*111 =11110000-1111+333000-9*12321 =11110000-1111+333000-123210+12321 =1111455321-124321 =11331000 .

简便方法计算 999x111+333x667 =(333*3)x111+333x667 =333*(3x111)+333x667 =333*333+333x667 =333*(333+667) =333x1000 =333000

999x111+333x667=333x(3x111+667)=333x(333+667)=333x1000=333000

999*111+333*667=333*333+333*(1000-333)=333*1000=333000

您好:999x111+333x667=3x333x111+333x667=333x333+333x667=333x(333+667)=333x1000=333000 如果本题有什么不明白可以追问,如果满意请点击右下角“采纳为满意回答” 如果有其他问题请采纳本题后,另外发并点击我的头像向我求助,答题不易,请谅解,谢谢.o(∩_∩)o,记得采纳,互相帮助 祝学习进步!
