Questions and key Most Chinese beginner learners of English have problems with numbers, particularly large numbers. Let’s start with computer first. If you have a little knowledge of computers, you might come across KB, MB, and GB. K is equal to 1,000 (actually 1,024 in computer science); M 1,000,000, that is 1,000 times 1,000. Therefore, you can see that if you manage to understand numbers within one thousand, then you are able to get larger numbers correctly with the help of commas. For example, when you hear three hundred and thirty seven million, you write 337 followed by two commas.
