Understanding "Zahlen in Worten"
Writing numbers in German can seem daunting because numbers under one million are written as one continuous, compound word. Additionally, German inverts the units and tens.
The "And" (und) Rule:
In English, 25 is "twenty-five". In German, you say the five first, add "und" (and), then say twenty: fünfundzwanzig.
Example Conversion:
1,234 EUR = eintausendzweihundertvierunddreißig Euro
