To say eleven, just combine "10" or seep and "1" or eel, and you have ship-eel. Twelve is ship-ee. Easy right? Can you say your telephone number now?
The other number system (hana, dool, set, etc) is for combining a number with an object-specific counter. These are the numbers you would use when counting a specific number of people, objects, or things.

Up until the number 19, the straightforward way of building up large numbers that you learned above for the "general number system" is used in this system as well. So "eleven" is "ten" or yul and "one" or hana, yul-hana. "Nineteen" is yul together with the number "nine" or ahop, yul-ahop.
