Numbers can be expressed in three forms. They are as follows:

- Standard form
- Expanded form
- Written form

Standard form: The standard form is nothing but the mathematical form of the number.

Example:

The number \(425\) - Standard form.

Similarly, \(8756, 369824, 587469123\) are also the standard forms of numbers.

Expanded form: Split a number according to their place value and expand it to show the value of each digit is called the expanded form.

Example:

For the same set of numbers \(425, 8756, 369824, 587469123\), the expanded form will be as follows:

Written form: This can be done by directly converting the expanded form to words.

Example:

For the same set of numbers \(425, 8756, 369824, 587469123\), all the three forms are listed below.

Standard form | Expanded form | Written form (Indian system) | Written form (International system) |

\(425\) | \(400+20+5\) | Four Hundred Twenty-Five | Four Hundred Twenty-Five |

\(8756\) | \(8000+700+50+6\) | Eight Thousand Seven Hundred Fifty-Six | Eight Thousand Seven Hundred Fifty-Six |

\(369024\) | \(300000+60000+9000+20+4\) | Three Lakh Sixty Nine Thousand Twenty Four | Three Hundred Sixty Nine Thousand Twenty Four |

\(587469123\) | \(500000000+80000000+7000000+\) \(400000+60000+9000+100+20+3\) | Fifty-Eight Crore Seventy Four Lakh Sixty Nine Thousand One Hundred Twenty Three | Five Hundred Eight Seven Million Four Sixty Nine Thousand One Hundred Twenty Three |
