Hanja for Cimi: 十 10 십

十 ten 10 십

Notice that 十 has both a horizontal and vertical stroke.

How would you write 20?   二十   (2 tens)

How about thirty?  三十

Well, isn’t that clever?

Note one more thing.  This character 十 has two strokes.  So does the character 二.  One of the ways to think about Hanja is how many lines does it take to draw the character.
