Numbers in English come in two flavours:

  • hundred, thousand,


  • 12 is a dozen
  • 20 is a score.
  • We say 99.94 is "ninety-nine point nine four"

Note Americans tend to say "one hundred thirty two" rather than "one hundred and thirty two"

1 billion used to be 1,000,000,000,000, but the Americans changed it to be merely 1,000,000,000. But they haven't told the Europeans, where 1,000,000,000 is a milliard (or similar).

Europeans often use different number separators so that "1,234.5" or "1 234.5" is written as "1.234,5"[1]

Students often need to practise thinking of numbers in English, as they will naturally default back to L1 thinking when reading numbers.
