When dealing with large figures we should be aware of the difference between American and British.
A thousand is always 1,000 and a million is always 1,000,000. After that things become less clear.
In the USA: 1,000,000,000 = a billion.
In Britain : 1,000,000,000 = one thousand million; 1,000,000,000,000= a billion
Anyway, keep the American way of dealing with billions and try to guess the answers of this questionnaire before watching a video to find out answers
