A table can be useful to look up how many zeros large numbers have. But, if you need to know how to write them, it helps to see them written out in all their glory. Ten: 10 1 zero Hundred: 2 zeros Thousand: 3 zeros Ten thousand 10, 4 zeros Hundred thousand , 5 zeros Million 1,, 6 zeros Billion 1,,, 9 zeros Trillion 1,,,, 12 zeros Quadrillion 1,,,,, 15 zeros Quintillion 1,,,,,, 18 zeros Sextillion 1,,,,,,, 21 zeros Septillion 1,,,,,,,, 24 zeros Octillion 1,,,,,,,,, 27 zeros Nonillion 1,,,,,,,,,, 30 zeros Decillion 1,,,,,,,,,,, 33 zeros.
The larger a numeral gets, the harder it becomes to count the digits. So, digits in large numbers are grouped in sets of three. For example, write one million as 1,, rather than The set of three starts as you move to the left of a decimal point the last zero. So, you write 10, rather than , Sometimes a space is used instead of a comma to separate digits.
While you might think that that one is pretty simple, just wait until you have to count 27 zeros for an octillion or zeros for a centillion. The whole amount sounds large if you apply it to money.
However, dreaming of becoming a millionaire is not as easy as it seems. A Forbes article from claims that a majority of Americans face a series of issues that likely prevent them from becoming full-fledged millionaires. You also have to save up for your rent, utility bills, and other daily expenses. However, we encounter that large value every day in populations, units of measurement, internet usage, video views, and so much more.
As of , about 7. Among those people, billionaires Bernard Arnault and Jeff Bezos keep moving up and down the top spot in the current list of the richest person in the world. As most math teachers would say, numbers play an important role in all our lives, especially in the lives of the rich.
In a billion, there are 9 zeroes. To simplify things, a billion has 3 groups of 3 zeros. If you apply for that big number of money, you can see why billionaires just love making more cash. Now that you know how many zeros are in a billion, learning about the value of a trillion and other larger values will be a breeze. Then again, you might just want to impress a friend or teacher. The digit zero plays an important role as you count very large numbers. It helps track these multiples of 10 because the larger the number is, the more zeroes are needed.
In the table below, the first column lists the name of the number, the second provides the number of zeros that follow the initial digit, and the third tells you how many groups of three zeros you would need to write out each number. A table like the one above can certainly be helpful in listing the names of all of the numbers depending on how many zeros they have. But it can be really mind-boggling to see just what some of those numbers look like.
Below is a listing—including all the zeros—for the numbers up to decillion—a little more than just half the numbers listed in the above table. Ten: 10 1 zero Hundred: 2 zeros Thousand: 3 zeros Ten thousand 10, 4 zeros Hundred thousand , 5 zeros Million 1,, 6 zeros Billion 1,,, 9 zeros Trillion 1,,,, 12 zeros Quadrillion 1,,,,, 15 zeros Quintillion 1,,,,,, 18 zeros Sextillion 1,,,,,,, 21 zeros Septillion 1,,,,,,,, 24 zeros Octillion 1,,,,,,,,, 27 zeros Nonillion 1,,,,,,,,,, 30 zeros Decillion 1,,,,,,,,,,, 33 zeros.
Reference to sets of zeros is reserved for groupings of three zeros , meaning they are not relevant for smaller numbers. We write numbers with commas separating sets of three zeros so that it's easier to read and understand the value.
For example, you write one million as 1,, rather than As another example, it's much easier to remember that a trillion is written with four sets of three zeros than it is to count out 12 separate zeroes. While you might think that that one is pretty simple, just wait until you have to count 27 zeros for an octillion or zeros for a centillion.
It is then that you will be thankful that you only have to remember nine and sets of zeros, respectively. The number googol termed by Milton Sirotta has zeros after it.
Here's what a googol looks like, including all of its required zeros:. Do you think that number is big? How about the googolplex , which is a one followed by a googol of zeros. The googolplex is so large it doesn't have any meaningful use yet—it is larger than the number of atoms in the universe. In the United States—as well as around the world in science and finance—a billion is 1, million, which is written as a one followed by nine zeros.
This is also called the "short scale.
