To express a range of numbers, Korean (and likely other Asian languages) will use a tilde instead of a dash or hyphen. To me, that better expresses that we’re talking about an indeterminate value or a range. Especially when we use ~ for “about”, as in ~$20 for something that costs $17.99 before tax, for example.

Dining out costs like 20~40 dollars per person!

Whereas “20-40” looks too similar to a subtraction equation or a hyphenated word to me.

Either the whole thing is a question or you need to break it up.

I’m curious if you can convince me otherwise though!
