Write the following in numbers in normal decimal notation?

To convert written numbers to normal decimal notation, we replace the words with the corresponding numerical digits. Here are some examples:

- "One" becomes "1".
- "Two" becomes "2".
- "Three" becomes "3".
- "Four" becomes "4".
- "Five" becomes "5".
- "Six" becomes "6".
- "Seven" becomes "7".
- "Eight" becomes "8".
- "Nine" becomes "9".
- "Ten" becomes "10".

For numbers beyond nine, we use a combination of digits. For instance:

- "Eleven" becomes "11".
- "Twelve" becomes "12".
- "Thirteen" becomes "13".
- "Fourteen" becomes "14".
- "Fifteen" becomes "15".
- "Sixteen" becomes "16".
- "Seventeen" becomes "17".
- "Eighteen" becomes "18".
- "Nineteen" becomes "19".

For numbers greater than nineteen, we combine the tens digit with a unit digit. Here are some examples:

- "Twenty" becomes "20".
- "Thirty" becomes "30".
- "Forty" becomes "40".
- "Fifty" becomes "50".
- "Sixty" becomes "60".
- "Seventy" becomes "70".
- "Eighty" becomes "80".
- "Ninety" becomes "90".

Note that for numbers above 99, we use the same naming convention. For instance:

- "One hundred" becomes "100".
- "Two hundred thirty-four" becomes "234".
- "Five thousand five hundred seventy" becomes "5,570".
- "One million" becomes "1,000,000".

By applying this conversion process, you can convert any written number into normal decimal notation.
