Question about numbers 0,4,7
I started learning hiragana and while i was at it i also started learning some basic stuff like colors and numbers.
I have two textbooks and in one numbers are like this: 0:零 rei, 4:四 yon and 7:七 shichi
and in other as: 0:ゼロ zero,4 し shi and 7:なな nana
Why is that is that because of a dialect, is one textbook incorrect or do each have some special uses?
