99.99X11.11+33.33X36.67=?

99.99×11.11+33.33×36.67
＝33.33×3×11.11+33.33×36.67
＝33.33×33.33+33.33×36.67
＝33.33×（33.33+36.67）
＝33.33×70
＝2333.1

99.99*11.11+33.33*36.67=3*33.33*11.11+33.33*36.67
=33.33*(11.11*3+36.67)
=33.33*(33.33+36.67)
=33.33*70
=2333.1

将99.99*11和33.33提取公因数33.33
99.99*11.11+33.33*36.67
=3*33.33*11.11+33.33*36.67
=33.33*(11.11*3+36.67)
=33.33*(33.33+36.67)
=33.33*70
=2333.1

99.99*11.11+33.33*36.67
=33.33*33.33+33.33*36.67
=33.33*（33.33+36.67）
=33.33*70
=2333.1

貌似你家么有计算机`?~````
