9.35＊77＋935－17.7＊3.5的简便算法

9.35＊77＋935－17.7＊3.5
=935＊0.77＋935－17.7＊3.5
=935*1.77-1.77＊35
=1.77*900
=1593

9.35＊77＋935－17.7＊3.5
=9.35*77+9.35*100-17.7*3.5
=9.35*(77+100)-17.7*3.5
=9.35*177-17.7*3.5
=17.7*93.5-17.7*3.5
=17.7*(93.5-3.5)
=17.7*90
=177*9
=177*(10-1)
=1770-177
=1593

9.35＊77＋935－17.7＊3.5
=93.5x7.7+93.5x10-17.7x3.5
=93.5x(10+7.7)-17.7x3.5
=93.5x17.7)-17.7x3.5
=(93.5-3.5)x17.7
=90x17.7
=177x9
=177x10-177
=1593
