1、2005*0.375-0.375*1949+3.75*2.4
=0.375×(2005－1949+24)
=0.375×80
=30
2、2006+200.6+20.06+2.006
=2.006×1000+2.006×100+2.006×10+2.006×1
=2.006×1111
=2228.666
=0.375×(2005－1949+24)
=0.375×80
=30
2、2006+200.6+20.06+2.006
=2.006×1000+2.006×100+2.006×10+2.006×1
=2.006×1111

2005*0.375-0.375*1949+3.75*2.4=2005*0.375-0.375(2005-56)+(0.375*10)*2.4
=2005*0.375-2005*0.375+56*0.375+0.375*24=0.375*80=30
2006+200.6+20.06+2.006=2.006*1000+2.006*100+2.006*10+2.006*1
=2.006*(1000+100+10+1)=2.006*2005*0.375-0.375*1949+3.75*2.4
=0.375(2005-1949+24)
=0.375x80
=30
=2006+200.6+20.06+2.006
=2006(1+0.1+0.01+0.001)
=2006X1.
=2005*0.375-2005*0.375+56*0.375+0.375*24=0.375*80=30
2006+200.6+20.06+2.006=2.006*1000+2.006*100+2.006*10+2.006*1
=2.006*(1000+100+10+1)=2.006*2005*0.375-0.375*1949+3.75*2.4
=0.375(2005-1949+24)
=0.375x80
=30
=2006+200.6+20.06+2.006
=2006(1+0.1+0.01+0.001)
=2006X1.

=2.006×1000+2.006×100+2.006×10+2.006×1
=2.006×1、原式=2005*（3/8）-1949*（3/8）+24*（3/8）=（2005-1949+24）*（3/8）=80*（3/8）=30
2、原式=（2006+200+20+2）+（0.6+0.06+0.006）=2228.666
=0.375×(2005－1949+24)
