Answer 1

这道题不太好用简便计算
具体计算过程如下所示
778×54+444×28
(780-2)×(50+4)+444×(30-2)
=780×50+780×4-100-8+444×30-888
=39000+3120-100-8+13320-888
=52320+3120-100-896
=54444

Answer 2

=778×54+444×28
=778×54+222×54
=54×(778+222)
=54×1000
=54000

Answer 3

778×54+444×28
=778×54+222×(54+2)
=54×(778+222)+222×2
=54000+444
=54444

Answer 4

=（777+1）*54+444*28
=777*54+54+444*28
=111*7*54*111*4*28+54
=111*（7*54+4*28）+54
=111*490*54
=111*（500-10）+54
=111*500-111*10+54
=55500-1110+54
=54390+54
=54444

Answer 5

=778×56－778×2+222×2×28
=(778+222)×56－778×2
=56000－1556
=4044
