Fun fact: Did you know that in some Asian countries they do not say "one hundred thousand" but rather they say "ten of ten thousands" instead?
True story: In Chinese, for example, there is a special character (万) for 10,000 which is pronounced as wan.
20,000 will be "2 wan", etc.
Now can you guess how they say 100,000 in Chinese?
Yes, that's right, you need to say "10 wan" ("ten of ten thousand").
Well, of course, you must also say that number "10" in Chinese as well: shi wan (十万).
