There are two types of numbers: cardinal and ordinal.

A cardinal number is a noun that indicates the amount of a countable thing. For example:

**أربعة****أولاد**(four children)There are twelve foundational cardinal numbers:

**واحِد**(one),**إثنان**(two),**ثَلاثَة**(three),**أربعَة**(four),**خَمسَة**(five),**سِتَّة**(six),**سَبعَة**(seven),**ثمانیَة**(eight**),****تِسعَة**(nine**),****عَشرَة**(ten),**مائَة**(hundred), and**ألف**(thousand).There are four types of cardinal numbers:

• Single: from one to ten, including a hundred and a thousand.

• Compound: from eleven to nineteen.

• Decimal: from twenty until ninety.

• Coupled: from twenty-one until ninety-nine.

- The rules relating single numbers are:

• One and two: they are masculine when the numbered object is masculine
and feminine when the numbered object is feminine. For example: **رجلٌ**
**واحدٌ** (one man) and **إمرَأةٌ** **واحدةٌ** (one woman).

• From three to ten: they are feminine when the numbered object is
masculine and masculine when the numbered object is feminine. For
example:**ٍثَلاثَةُ** **أولادِ** three boys) and **ثَلاثُ** **والداتٍ**
(three girls).

• A hundred and a thousand: they remain the same regardless if the
numbered object is masculine or feminine. For example: **مائةُ**
**صبيٍّ** (a hundred boys) and **مائة** **فتاةٍ** (a hundred girls).

The rule regarding compound numbers is that the first part of the number follows the rules for single numbers and the second part follows the numbered object in gender. For example:

**عَشَرَ****عَدَداً**(eleven numbers) and**خَمسَة****عَشَرَ****بَیتاً**(fifteen houses).The rule regarding decimal numbers is that they remain the same regardless of the gender of the numbered object. For example:

**عِشرونَ****رَجُلاً**(twenty men) and**عِشرونَ****امرَةً**(twenty women).The rule regarding coupled numbers is that the first part of the number follows the rules for single numbers and the second part remains the same regardless of the gender of the numbered object. For example:

**واحد****و****عشرون,****اِثنان****و****عشرون**, and**ثلاثةٌ****و****عشرون**for masculine objects and**واحدة****و****عشرون**,**اثنتان****و****عشرون**and**ثلاثٌ****و****عشرون**for feminine objects.The rules of numbers in respect to vowel signs are:

• Two: follows the rules regarding dual forms. For example: **اثنان**
and **اثنَین** (two masculine) and **اثنتان** and **اثنتَین** (two
feminine).

• Decimal: follows the rules of sound masculine plurals. For example:
**عِشرون** and **عِشرین** (twenty).

• Compound: The first part of the number is indeclinable with a
*fathah*. For example: **جَلَسَ** **أحَدَ عَشَرَ** **رَجُلاً** **علیَ**
**أحَدَ** **عَسَرَ** **کُرسیاً** (eleven men sat on eleven chairs).

• The rest of the numbers: follow the rules regarding other nouns. For
example: **جاءَ** **رجالٌ** **ثلاثةٌ** **حاملینَ** **أربعةَ** **کُتُبٍ**
(three men came carrying four books).

- The rules of the numbered object are:

• From three until ten: the numbered object is plural in the genitive
state. For example: **جاءَ** **ثلاثةٌ** **أولادٍ** (three boys came).

• From a hundred to a thousand: the numbered object is singular and in
the genitive state. For example: **جاءَ** **مئةُ** **ولدٍ** (a hundred
boys came).

• From eleven to ninety-nine: the numbered object is singular and in the
accusative state. For example: **جاءَ** **أربعةَ** **عَشَرَ** **وَاداً**
(fourteen boys came).
