问题描述:
191*192192-192*191191等于几
答
原式=191*(192000+192)-192*(191000+191)
=191*192000-192*191000
=1000*(191*192-192*191)
=0
答
191*192192-192*191191
原式=191*(191191+1001)-191191×(191+1)
=191×191191+191191-191191×191-191191×1
=0
经计算器验算正确

答
191*192192-192*191191
=191*192192-(191+1)*191191
=191*(192192-191191)-191191
=191*1001-191191
=0
