11-19: X + belas (sebelas, dua belas...). 20-99: X + puluh (dua puluh, tiga puluh...). 100 = seratus, 1000 = seribu.

The se- prefix means 'one': sepuluh = one-ten, seratus = one-hundred.

Practice Exercises
Forget 'se-' prefix: say 'satu puluh' instead of 'sepuluh'. Don't add plural markers with numbers. 🇬🇧 English speakers: More regular than English. 'Se-' is the main new concept.

Common Error Patterns

Said 'satu puluh' instead of 'sepuluh' or 'satu ratus' instead of 'seratus'

For the number 1 in compounds, use 'se-': sepuluh (10), sebelas (11), seratus (100), seribu (1000).

Added plural marker (orang-orang) after a number

Numbers already imply plurality. Say 'tiga orang' (three people), never 'tiga orang-orang'.

Saya dua puluh lima tahun.

I am twenty-five years old.

Numbers read left to right: 25 = dua puluh (20) + lima (5). 'Tahun' = years.

Harganya lima ribu rupiah.

It costs five thousand rupiah.

'Harganya' = the price (-nya = the). 'Lima ribu' = 5,000. 'Rupiah' = Indonesian currency.

Ada tiga orang di sini.

There are three people here.

'Ada' = there is/are. No number agreement needed: 'tiga orang' — 'orang' doesn't change.
