9.99*2.22+3.33*3.34 怎么简便计算?
9.99*2.22+3.33*3.34 怎么简便计算?
9.99*2.22+3.33*3.34
=3.33*3*2.22+3.33*3.34
=3.33*(6.66+3.34)
=3.33*10
=33.3
9.99*2.22+3.33*3.34
=3.33*3*2.22+3.33*3.34
=3.33*(6.66+3.34)
=3.33*10
=33.3
9.99×2.22+3.33×3.34 =3.33*6.66+3.33*3.34 =3.33*(6.66+3.34) =3.33*10 =33.3
9.99*2.22+3.33*3.34
=3.33*3*2.22+3.33*3.34
=3.33*(6.66+3.34)
=3.33*10
=33.3
