Can I just say 二五 when I’m talking or counting instead of 二十五? Will it make a difference between the two of them? Or is it because 二五 is like everyday speech (informal) and 二十五 (formal) for writing?
I watched 奔跑吧第 “Keep Running” show in order to learn and improve my chinese. I remembered in one of the episode of the show, the members were counting without 十 between numbers. I’m trying to learn the “everyday” chinese by watching chinese dramas and variety shows in order to improve my comprehension and speech.
