I'm reading the Japanese version of _Harry Potter and the Philosopher's
Stone_. When Oliver Wood is explaining Quidditch rules to Harry, he says:

> 輪に入るたびに一〇点だ。

Why say 「一〇点」 instead of 「十点」? How do I read it? 「イチゼロテン」?「ジュウテン」？「Tenてん」？

Is this something specific to sports? The only sport I follow is football, and
since I have heard weird things like commentators saying 「いちななーいちはち」 for the
'17-'18 Premier League season, I suspect that might be the case.

Why use 「一〇点」 instead of 「十点」 and how do I read it?
I suppose you're reading the book on paper (or Kindle-like terminal), where
the text is written vertically. In _vertical mode_ , the positional notation
of _kanji numerals_ are used as much as how Arabic numerals are used in
horizontal mode.

> 一〇点 _10 points_ vs. 十点 _ten points_

It doesn't affect the pronunciation, so you're just going to read it out じゅってん
(or じってん, prescriptively). Something like いちぜろてん is rarely used unless you're
a pilot or the base is other than ten.
