99乘99加199怎样简便运算

99乘999加199的简便计算法。 99*999+199 =99*999+99+100 =99*(999+1)+100 =99*1000+100 =99000+100 =99100

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

99X999+199 =99X999+100+99 =99X(999+1)+100 =99X1000+100 =99000+100 =99100

99x99+199 =99x99+99+100 =99x(99+1)+100 =99x100+100 =100x(99+1) =100x100 =10000

99x99+199 =99x99+99+100 =99x(99+1)+100 =9900+100 =10000

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

99×99+199=99²+2×99×1+1²=﹙99+1﹚²=100²=10000

解:99×999+199 =99×(1000-1)+199 =99000-99+199 =99000+100 =99100

99x999+199 =99x(1000-1)+199 =99x1000-99+199 =99100 希望我的回答能帮助你, 如有帮助请采纳
