I think Duolingo should accept the colloquial drop. I've not heard it said with the 一 all that much
The notes even say to drop it: https://www.duolingo.com/skill/zs/Payment/tips-and-notes
Just report it and hope the volunteers get to it eventually :)
Thanks. I always hear and speak it dropped. Vaguely remember a beginner chinese class 8 years ago telling me this rule.
Does it mean newspapers would write it 一十 instead of 十? And does it cover all instances of 10 or just for numbers bigger than 100? For example, is it grammatically correct to say 价钱是一十块? Thanks.
Was in China for 5 years and not once did I year them say 一十。even my chinese keypad thinks its wrong
I have been in China 11 years and not heard it spoke like this. They drop the 一
