## How do we write big numbers

To write a number, the digits are placed from left to right under the places labelled as Units, Tens, Hundreds, Thousands… etc., and read accordingly. For example, consider number 393071425. The number is read as Three hundred and ninety-three million,  seventy-one thousand four hundred and twenty five.

### Commas in number

To read easily and understand the value we write big numbers with commas separating sets of three zeros. For example, you write one million not as 1000000. but as 1,000,000.

It’s easier to remember that a billion is written with four sets of three zeros than it is to count out 9 separate zeroes.

### Scientific way of writing numbers

Scientific notation is a convenient way of writing very large or very small numbers so that it is easier to use in computations and  compare A number written in scientific notation is of the form a * 10n where a is the non-zero number between 1 and 10 and n is the number of digits up to the decimal point for example

700 is written as 7 × 102

4,900,000,000 is written as 4.9 × 109

In scientific notation, million is written as 1×106, billion as 1×109 and trillion as 1×1012

## How many Zeros in Millions, Billions, Trillions?

After 100, The most common way to get next bigger number is the power of 10 increases by 3 for each new number, which means you add three extra zeros to the end of the number to get the next number. This happens till Quadragintillion or 10 ^123 and then it increases in powers of 30.

## Long scale and short scale for Large Numbers

There are two ways of saying big numbers Short scale and Long scale.

For whole numbers smaller than 1,000,000,000 (10^9 ), such as one thousand or one million, the two scales are identical. For larger numbers, starting with 10^ 9, the two systems differ. The long scale increases by powers of one million, whereas the short scale increases by powers of one thousand.

For example, In science and finance and in the USA a trillion is 1,000 billion, which is written as a one followed by 12 zeros. This is also called a short scale.

But there is also a long scale, which is used in France and was previously used in the United Kingdom, in which a trillion means 10 to the power 18 – thus, a million million million (tri- as in tricycle, tripod, triangle, etc.)

Often in Europe, you hear “Milliarde” in German, “miljard” in Dutch, “milyar” in Turkish and “миллиард” in Russian which are standard usage when discussing financial topics. The names ending in -illiard for numbers of the form 10^6n+3. Ex 10^9 is Milliard while 10^16 is Billiard

Due to its dominance in the financial world by the US dollar, short scale was adopted for official United Nations documents.
