"Different ways to write a number" is the much required stuff for the children who study  math in primary level.

Three different ways to write a number

Standard form :

This is a way to write a number showing only its digits. This is the form we are most familiar with and see most often.

Example : 5,673,289

Expanded form :

This is a way to write a number as the sum of the value of  its digits. This form indicates the place value of each digit  in the number. 

Example :

5,000,000 + 600,000 + 70,000 + 3,000 + 200 + 80 + 9

= 5,673,289

For example,

Word form :

This is a way to write a number in words only, also need to include commas separating the periods. If there are commas in standard form, there must be commas in word form.

Example :

Five million, six hundred seventy three thousand, two hundred eighty nine.

Examples

Example 1 :

Convert the number given below into standard form.

Two million, five hundred seventy three thousand, two hundred seventy one.

Solution :

Hence, standard form of the given number is, 2,573,271

Example 2 :

Convert the number given below into standard form.

Seventy five  million, sixty three thousand, five hundred.

Solution :

Hence, standard form of the given number is, 75,063,500

Example 3 :

Convert the number given below into word form.

56,623,589

Solution :

Hence, the expanded form is,

Fifty six million, six hundred twenty three thousand, five hundred eighty one.

Example 4 :

Convert the number given below into expanded form.

7,856,254

Solution :

Hence, the expanded form is,

7,000,000+800,000+50,000+6,000+200+4 = 7,856,254

Example 5 :

Convert the number given below into standard form.

2,085,162

Solution :

Hence, the expanded form is,

2,000,000+80,000+5,000+100+60+2 = 2,085,162

In examples 4 & 5, to get expanded form, each digit of the number to be multiplied by the value of its place and add them together.

For example, in 4562, 4 is at thousands place. So 4 has to be multiplied by 1000 and we get 4000.

In the same way, we have to multiply each digit by the value of its place to expanded form.
