The number system in Chinese cannot be simpler:
1. The number from 1 to 9 is 一二三四五六七八九
2. The number 10 is 十
3. For 20, 30, 40, you just use simple combinations: 二十，三十，四十, etc.
4. 21 is 二十一, 35 is 三十五, 99 is 九十九, just like this.
but it becomes too long when we write big numbers doesn'it ? do chinese people use Arabic numbers instead of the characters ?
Yes they do, to tell large numbers and quantities as phone numbers, population, money, etc.
They also use Arabic numbers with addresses, but there the usage is mixed.
yes you are right. big numbers get a bit longer... but they have different also groups, like they use hundreds, thousands and 10 thousands. like english ten hundreds for thousands.
Thank you. I think duo should start number lessons with these kind of sequences instead of random order, I had the same problem in Danish
Actually, before u start a "trial", there is an option that explains all u are going to find in the chapter
I find it very useful because u don't just exercise without seeing all u are supposed to exercise
not sure if this is still in Beta or indeed if anyone checks the comments, but personally I think it would be helpful if they could cover the english meanings of the chinese words early in the lesson. Until about 60% of the way through the lesson you only learn the chinese character and its pinyin pronunciation without any clue as to the actual meaning.
Having said that, I'm very excited about chinese being in Duo and looking forward to the rest of the course :-)
I accidentally mistyped this as "79" and it still read as right? You might want look into that
