Hey guys, today I picked up a book in Barnes and Noble called, "250 Essential Japanese Kanji Characters: Volume 1" and I am enjoying it a lot so far, however there is a question I have for you guys.
When it is talking about the reading of the numbers, it has things like this:
futa-tsu, ni
ふた•つ、ニ
two
My question is what does the ____•つ part mean? It has it in the readings for every number except 十 and 百.
Thanks!
EDIT:
Picture of what I mean.
