阿拉伯数字是西方语言或欧洲形式的印度-阿拉伯数字。印度-阿拉伯数字系统是由古代印度的婆罗米人发明，后经由阿拉伯传入西方。很多语言都引用了此系统，但是都根据自己语言的字体要求而改造，所以实际上现在有很多种被称为“阿拉伯数字”数字字符。此条目是关于汉语里通称的“阿拉伯数字”，也是当代世界最通用的阿拉伯数字，也就是欧洲文字所改造的印度-阿拉伯数字。

记数法[编辑]
现代所称的阿拉伯数字以十进制为基础，采用0、1、2、3、4、5、6、7、8、9共10个计数符号。采取位值法，高位在左，低位在右，从左往右书写。借助一些简单的数学符号（小数点、负号等），这个系统可以明确的表示所有的有理数。为了表示极大或极小的数字，人们在阿拉伯数字的基础上创造了科学记数法。
一般也用阿拉伯数字表示其它进制的数，用时选一部分数字或增加几个数字。
阿拉伯数字始创于印度（但当时没有0），后来传到中东地区的阿拉伯地区，而得此名。现在它已成为目前使用最广泛的记数系统，通行于全世界。

Arabic numerals
From Wikipedia, the free encyclopedia
The system was adopted by Arab mathematicians in Baghdad and passed on to the Arabs farther west. There is some evidence to suggest that the numerals in their current form developed from Arabic letters in the Maghreb, the western region of the Arab world.[5] The current form of the numerals developed in North Africa, distinct in form from the Indian and eastern Arabic numerals. It was in the North African city of Bejaia that the Italian scholar Fibonacci first encountered the numerals; his work was crucial in making them known throughout Europe and then further to the Europeans who spread it worldwide. The use of Arabic numerals spread around the world through European trade, books and colonialism.
The term Arabic numerals is ambiguous. It most commonly refers to the numerals widely used in Europe and the Americas; to avoid confusion, Unicode calls these European digits. Arabic numerals is also the conventional name for the entire family of related numerals of Arabic and Indian numerals. It may also be intended to mean the numerals used by Arabs, in which case it generally refers to the Eastern Arabic numerals. It would be more appropriate to refer to the Arabic numeral system, where the value of a digit in a number depends on its position.
Although the phrase "Arabic numeral" is frequently capitalized, it is sometimes written in lower case: for instance, in its entry in the Oxford English Dictionary,[6] which helps to distinguish it from "Arabic numerals" as the East Arabic numerals specific to the Arabs.

Main article: History of the Hindu–Arabic numeral system
The decimal Hindu-Arabic numeral system was developed in India by AD 700.[7] The development was gradual, spanning several centuries, but the decisive step was probably provided by Brahmagupta's formulation of zero as a number in AD 628. The system was revolutionary by including zero in positional notation, thereby limiting the number of individual digits to ten. It is considered an important milestone in the development of mathematics. One may distinguish between this positional system, which is identical throughout the family, and the precise glyphs used to write the numerals, which varied regionally. The glyphs most commonly used in conjunction with the Latin script since early modern times are 0 1 2 3 4 5 6 7 8 9. The first universally accepted inscription containing the use of the 0 glyph in India is first recorded in the 9th century, in an inscription at Gwalior in Central India dated to 870. Numerous Indian documents on copper plates exist, with the same symbol for zero in them, dated back as far as the 6th century AD, but their dates are uncertain. Inscriptions in Indonesia and Cambodia dating to AD 683 have also been found.[8]

穆斯林鼓励生育的，穆斯林家庭4，5个孩子都是很平常的事，穆斯林人口增长速度远远超过大家的想象
因为你也是穆斯林，所以你觉得没有大问题，我说的对么？

你错了。
还有不少这样说华人中国人的你信不？
