So, are we (Czechia) the only ones who use more than one way?
90+9 (ninety-nine literally) is the formal way to do it, while 9+90 (nine-and-ninety literally) is the informal way. You can easily hear both of the ways used in one sentence.
Norway as well. 90+9 is the official way, 9+90 is the way from when the Germans occupied the country. Both are still used. The map also says Georgia and Finland also use two variations.
