To say high numbers in English, you need to learn three main words: hundred, thousand, e million. These words help you build any large number. For example, 100 é one hundred, 1,000 é one thousand, e 1,000,000 é one million. When you combine them, like 1,234, you say one thousand, two hundred and thirty-four. Remember to use and after hundred in British English. Understanding these basic patterns will help you read and speak large numbers clearly and correctly in English.

How Do We Say Numbers from 100 to 999?

For numbers between 100 e 999, we use the word hundred.

You always say the number before hundred. Then, for numbers after hundred, we often use the word and (especially in British English).

  • 100 é one hundred.
  • 250 é two hundred and fifty.
  • 789 é seven hundred and eighty-nine.

How Do We Say Numbers from 1,000 to 999,999?

For numbers from 1,000 up to 999,999, we use the word thousand.

We use a comma (,) to separate thousands from hundreds. This makes numbers easier to read.

  • 1,000 é one thousand.
  • 5,000 é five thousand.
  • 10,000 é ten thousand.
  • 25,400 é twenty-five thousand, four hundred.
  • 123,456 é one hundred and twenty-three thousand, four hundred and fifty-six.

How Do We Say 1,000,000?

When a number reaches 1,000,000, we use the word million.

Just like with hundred e thousand, you say the number before million.

  • 1,000,000 é one million.
  • 2,000,000 é two million.

When Do We Use 'and' in Numbers?

In British English, we use and after hundred e thousand when there are more numbers that follow.

  • 101: one hundred and one.
  • 520: five hundred and twenty.
  • 1,005: one thousand and five.
  • 2,345: two thousand, three hundred and forty-five.

If the number ends exactly on a hundred ou thousand, you do not use and.

  • 200: two hundred. (NOT two hundred and)
  • 3,000: three thousand. (NOT three thousand and)
