This video and picture are helpful to be able to read and write the big numbers. We don't normally write numbers with words, but it's possible to do this, and of course, this will show how we say the numbers.
For example:
| 1,011 | one thousand eleven | |
| 21,011 | twenty-one thousand eleven | |
| 721,011 | seven hundred twenty-one thousand eleven |
| 1,256,721 | one million two hundred fifty-six thousand seven hundred twenty-one | |
| 31,256,721 | thirty-one million two hundred fifty-six thousand seven hundred twenty-one | |
| 631,256,721 | six hundred thirty-one million two hundred fifty-six thousand seven hundred twenty-one |
