276+228+353+219
(375+1034)+(966+125)
答
0.2222x2.4+0.2222x7.6
=2.222
56x1.02-1.4x40x0.02
=56x(1.02-0.02)
=56
答
0.8888*0.6+0.2222*7.6=0.2222*0.6*4+0.2222*7.6=0.2222*2.4+0.2222*7.6=0.2222*（2.4+7.6）=0.2222*10=2.22256*1.02-1.4*0.8 =56*（1+0.02）-1.4*0.8=56*1+56*0.02-1.4*0.8=56+5.6*0.2-1.4*0.8=56+0.8*7*0.2-1.4*0....
