同样祝你中秋快乐
17.8/(1.78*4)
=1/4
6.3+4.82+3.7-0.82 =(6.3+3.7)+(4.82-0.82)
=10-4
=6
48.4+2.78+51.6-0.48
=(48.4+51.6)+(2.78-0.48)
=100+2.3
=102.3

333*334+999*222
=333×334+333×3×222
=333×(334+3×222)
=333×(334+666)
=333×1000
=333000
2.22*9.9+6.66*6.7
=2.22×3×3.3+6.66×6.7
=6.66×3.3+6.66×6.7
=6.66×(3.3+6.7)
=6.66×10
=66.6

17.8/(1.78*4) =(17.8/1.78)/4=10/4=2.5
6.3+4.82+3.7-0.82=(6.3+3.7)+(4.82-0.82)=10+4=14
48.4+2.78+51.6-0.48=(48.4+51.6)+(2.78-0.48)=100+2.3=102.3
333*334+999*222=333*334+333*3*222=333*(334+666)=333*1000=333000
2.22*9.9+6.66*6.7=6.66*(3.3+6.7)=6.66*10=66.6
