How many digits are there in a million

Knowing how to write ordinary large numbers is useful for science or math class or your bank account, if you are rich. Use your knowledge of the gigantic numbers to impress your friends.

While ten and a hundred get their own name, larger numbers are based on groups of three zeros. This table gives the name for the groups of zeros in a number. 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. View answers. Andrew Mckenna Pro Online lessons. William Hide Pro Online lessons. Tolu Ogunseye Pro Online lessons. Sara Zia-Gharib Online lessons. Share Need help with Maths? Find a tutor now.

The exception is the subtracted numerals, if a numeral is before a larger numeral, you subtract the first numeral from the second. This only works for one small numeral before one larger numeral - for example, IIX is not 8, it is not a recognized roman numeral.

There is no place value in this system - the number III is 3, not Each digit can only count up to the value of one less than the base. Have ever wondered how many zeroes are in a million? A billion? A trillion?

Do you know how many zeros there are in a vigintillion? Someday you may need to know this for science or math class. 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
