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. <br/><br/>So, I would like to ask you guys to teach me how to write or say those numbers in English.<br/><br/>E.g.: 10,000.<br/><br/>E.g.: 100,000.<br/><br/>E.g.: 52,500.<br/><br/>E.g: 789,000.<br/><br/>Thanks very much.
