To answer this question, we need to look at the roots of each place value: the mil in million represents one, the bi in billion equals two, the tri in trillion equals three, and so on. This is a general equation which represents place value written in exponential notation. Here's an example:. The largest named number I could find is googolplex. This number was coined by Edward Kastner in His nine year old nephew coined the term googol to represent 10 , which he believed to be the largest number in the universe.
Kastner then created googolplex to show him that there is no largest number because any number can be made larger by performing operations to it. It is this concept that mathematicians are refering to when we use the term infinity. How long would it take to count to a million? A billion? If each count was one second long, it woud take 12 days to count to a million and 32 years to count to a billion. In fact, if you started counting when the universe was first formed you would only be at approximately ,,,,, or about quadrillion.
There are more place values listed below:. Place Values After Million If you asked a friend or relative what place value comes after a million, what would their answer be? Here are some place values greater than a million: Million : 1,, Billion : 1,,, Trillion : 1,,,, Quadrillion: 1,,,,, Quintillion : 1,,,,,, Nonillion : 1,,,,,,,,,, Decillion: 1,,,,,,,,,,, Googol: 1 followed by zeros Centillion : 1 followed by zeros Googolplex: 1 followed by a googol zero s How are these numbers formed?
What is the biggest number? 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. There is also a "long scale," which is used in France and was previously used in the United Kingdom, in which a billion means one million million. According to this definition of a billion, the number is written with a one followed by 12 zeros. The short scale and long scale were described by French mathematician Genevieve Guitel in Smith, Roger.
