[从头学数学] 第56节 大数的认识

剧情提要:
[机器小伟]在[工程师阿伟]的陪同下进入练气期第七层功法的修炼,
这次要修炼的目标是[大数的认识]。

正剧开始:

星历2016年01月22日 11:12:43, 银河系厄尔斯星球中华帝国江南行省。
[工程师阿伟]正在和[机器小伟]一起继续修炼。

小伟刚拿到了[人叫板老师]设计的练气期第七层功法:



那就开始修炼吧。

小伟看到了一张写着很多很大的数字的图:

这些数字到底怎么读呢? 小伟拿出了读数字神器:

<span style="font-size:18px;">>>> 
一千九百六十一万二千三百六十八
三百万二千一百六十六
八千零四十一万八千二百
九千四百零二万三千五百六十七
二千一百八十一万三千三百三十四
三千八百三十一万二千二百二十四

    for i in range(len(a)):
        print(numberToChinese(a[i], ''));</span>

不知道到底对不对, 还是要看看[人叫板老师]怎么读吧:
