In this lesson, we'll learn how to write numbers up to eight digits in words. We start by considering two-digit numbers.
Suppose we want to write the number in words. We start by writing down its place value chart.
| tens | ones |
Now, we write the number in words as follows:
The number has tens, so we write "fifty," followed by a hyphen:
"fifty-"
The number has ones, so we add "six":
"fifty-six"
Therefore, the number written in words is fifty-six.
Watch Out! Don't forget to include the hyphen!

Write the number in words.
To write a two-digit number (greater than ) in words, we
write the tens part, followed by a hyphen
then, write the ones part.
Let's write down the place values of
| tens | ones |
Now, we write the number in words:
The number has tens, so we write "eighty," followed by a hyphen:
"eighty-"
The number has ones, so we add "one":
"eighty-one"
Therefore, the number written in words is eighty-one.

Let's suppose we want to write the number in words.
We start by writing down its place value chart:
| hundreds | tens | ones |
Now, we write the number in words:
The number has hundreds, so we write "two" followed by "hundred":
"two hundred"
The number has tens and ones, so we add "thirty-seven":
"two hundred thirty-seven"
Therefore, the number written in words is two hundred thirty-seven.
Write the number in words.
To write a three-digit number in words, we
write the number of hundreds, followed by "hundred,"
then, write the tens and ones part.
Let's write down the place values of
| hundreds | tens | ones |
Now, we write the number in words:
The number has hundreds, so we write "six" followed by "hundred":
"6 hundred"
The number has tens and ones, so we add "seven":
"six hundred seven"
Therefore, the number written in words is six hundred seven.

Suppose we want to write in words. Let's start by splitting the number into its so-called periods (parts of the number separated by commas):
To express a four-digit number in words, we consider each period from left to right:
has ones only, and this digit is in the thousands place. So, we write "eight" followed by "thousand,":
"eight thousand,"
has hundreds, tens, and ones. So, we add "two hundred thirty-six":
"eight thousand, two hundred thirty-six"
Therefore, the number written in words is eight thousand, two hundred thirty-six.
We can use the same method to write down any number with four, five, or six digits in words. Let's see another example.
Write the number in words.
Notice that the highest-value digit is in the ten-thousands place.
Let's start by splitting the number into its periods:
Let's now look at each period:
has tens and ones. So, we write "thirty-two" followed by "thousand,":
"thirty-two thousand,"
has hundreds, tens, and ones. So, we add "forty-two":
"thirty-two thousand, forty-two"
Therefore, the number written in words is thirty-two thousand, forty-two.
The number $29,451$ written in words is

|
two hundred ninety thousand, four hundred fifty-one |
The number $312,516$ written in words is

c
|
three hundred twenty-two thousand, five hundred sixteen |
|
d
|
three hundred twenty-two thousand, five hundred sixty |
|
e
|
thirty-one thousand, five hundred sixteen |
Let's write the following number in words:
To express a seven-digit number in words, we consider each period from left to right:
has ones only, and this digit is in the millions place. So, we write "two" followed by "million,":
"two million,"
has hundreds, tens and ones. So, we add "six hundred thirty-two," followed by "thousand,":
"two million, six hundred thirty-two thousand,"
has hundred, tens and ones. So, we add "one hundred twenty-five":
"two million, six hundred thirty-two thousand, one hundred twenty-five"
Therefore, the number written in words is two million, six hundred thirty-two thousand, one hundred twenty-five.
We can use the same method to write down any number with seven, eight, or nine digits in words. Let's see another example.
Write the number in words.
Notice that the highest-value digit is in the ten-millions place.
Let's start by splitting the number into its periods:
Let's now look at each period:
has ten and ones. So, we write "fifteen," followed by "million,":
"fifteen million,"
has tens and one. So, we add "eighty-one," followed by "thousand,":
"fifteen million, eighty-one thousand,"
has ten and ones. So, we add "twelve":
"fifteen million, eighty-one thousand, twelve"
Therefore, the number written in words is fifteen million, eighty-one thousand, twelve.
