**Koreans use 2 different sets of numbers, depending on the situation
->Korean numbers and Chinese numbers.
1. Korean numbers(Pure)
-Use the Korean forms for the number of items(counting) , age and time..
There are two different forms of one, two, three and four in Korean numbers..
We use the second one which is in a parenthesis when we use numbers
with other words like 개/gae/ (when we count items we use it and it means piece) ,
살/sal/(When we say age we use it together and it means "-years old"),
시/si/ (When we say time we use it and it means O'clock) and so on..
Ex)The number of items: 한 개, 두 개, 세 개, 네 개, 다섯 개..(개-piece/item)
Age: 한 살, 두 살, 세 살,.., (살-years old)
Time: 8:00 여덟 시( 시-O'clock),..
but if you simply count without using 개/gae/ then use the first form..
->하나, 둘, 셋 , 넷,...
2. Chinese numbers(Sino)
. -Use the Chinese forms for dates, money, addresses, phone numbers and numbers above 100.
Ex) Date: May, 7-> 오월칠일
Money: 일원, 이원, 삼원,...(원/won/-won)
