For many learners of English like me, they always experience problems writing or saying numbers in English such as 50,000, 500,000 and the like.
So, I would like to ask you guys to teach me how to write or say those numbers in English.
E.g.: 10,000.
E.g.: 100,000.
E.g.: 52,500.
E.g: 789,000.
Thanks very much.
