Grammar Rule in 30 Seconds
Indonesian numbers 11-100 follow a simple 'base + suffix' pattern, making them incredibly easy to learn.
- 11-19 use the suffix '-belas' (e.g., 'tiga' + 'belas' = 'tigabelas').
- 20-99 use the suffix '-puluh' for tens (e.g., 'dua' + 'puluh' = 'duapuluh').
- For numbers like 21-99, add the unit after the ten (e.g., 'duapuluh satu').
