...the number 250258?

Is it iki yuz elli bin iki yuz elli sekiz?

Thank you.

 Aynen öyle! Exactly right!

Yes!

Other ways to tell it

2 by 2: yirmi beş - sıfır iki - elli sekiz

3 by 3: iki yüz elli - iki yüz elli sekiz

On an invoice, it should be written without any spaces in between

250258 = ikiyüzellibinikiyüzellisekiz

Thank you both! I got it right!
