Since I primarily use English despite being a native German speaker I always get those jumbled up and it bugs me so much. People dictate long numbers in sets of two or three digits, but instead of saying the digits, they say them as numbers. Then it's like "3 & 40" and I write 34 because my brain goes "first number, first digit" until I notice that I made this error again and have to correct it. It takes way more mental effort than it should and it annoys me that so many people say these as numbers instead of as actual sets of digits, which wouldn't be a problem in most other languages, but nooooo of course we need to add a good ol' switcheroo right at the end there
