Me as a foreign mother tongue find it really annoying, so I count in my head in my mother language.
There also has been a study, no matter if forward or backwards.. the first language you learned to count will be the language you use for counting in your head for the rest of your counting life
Isn't that cool? Never noticed, now Always pay attention to :)
I’m split about 50/50 with German (native and residence) and English counting. But when I count in German and write numbers, I tend to make more mistakes because of them being "backwards" :(
I also do most math in my native language, Spanish. When I'm silent reading text in English, most of the times I "say" the numbers in Spanish, but now always. Anyway, I have more intuition about numbers in Spanish, so even if I read it in English I may translate a few milliseconds later if I must think about it.
I can do some elementary calculations in English, like 2+3=5. But for more complicated stuff like the second derivative of x^3 I must switch to Spanish and translate the result.
