99*99+199的简便计算怎么写

99*99+199 =99x99+99+100 =99x(99+1)+100 =99x100+100 =100x(99+1) =100x100 =10000 亲,请【采纳答案】,您的采纳是我答题的动力,谢谢。

99×100+199-99 =9900+100 =10000

199+99*99 =100+99+99*99 =100+99*(1+99) =100+99*100 =100+9900 =10000

99×99+99+100=99×100+100=100×100=10000

199+99×199 =199×(1+99) =199×100 =19900

99乘99加199 =99*99+199 =99*99+99+100 =99*(99+1)+100 =99*100+100 =(99+1)8100 =100*100 =10000

99*(100-1)+199=99*100-99*1+199=9900+100=10000改了,我的结果正确

99×99+199 =99×99+99+100 =99×(99+1)+100 =99×100+100 =(99+1)×100 =100×100 =10000

=(100一1)^2+199 =10000一200+1十199 =10000

199×99+99 =99(199+1) =99*200 =(100-1)*200 =20000-200 =19800
