333✘666怎么简便计算？

Question

如题所述

Answer 1

计算步骤如下:333×666

=333×333×2

=111×3×333×2

=111×999×2

=[111×（1000-1）]×2

=[111000-111]×2

=222000-222

=221778

Answer 2

先把333化成算式3x111，把666化成6X111从而

333Ⅹ666
=3x111x111x6
=3X6x111x111
=18X12321
=221778

Answer 3

333×666这样简便计算：
333×666
=333×3×222
=999×222
=（1000-1）×222
=1000×222-1×222
=222000-222
=221778

Answer 4

333×666
=333×3×222
=999×222
=（1000-1）×222
=1000×222-1×222
=222000-222
=221778

Answer 5

333×666
=333×3×222
=999×222
=(1000－1)×222
=222000－222
=221778
