hi! i just started learning sino-korean numbers but i'm not quite sure when to use them since google is telling me quite different things.

so far i believe it's being used for:
- giving phone numbers
- room numbers, floor numbers
- years/centuries
- page numbers
- doing math
- dates (day, week, month)
- minutes, seconds
- servings
- money
- numbers over 99

is that correct? did i miss anything or do i need to correct something?

thanks for the help! :D
