Persian Braille
Persian Braille (Persian: بریل فارسی) is the braille alphabet for the Persian language. It is largely compatible with Arabic Braille, which may be found (in uncontracted form) within Persian Braille texts. There are a few additional Persian letters that do not exist in Arabic. Persian Braille is read from left to right, following the international convention. Numbers are also left to right, rather than switching direction as they do in printed Arabic. Persian Braille charts Letters Numbers and arithmetic Numbers are the same as in English Braille. Arithmetical symbols are introduced by a separate braille prefix. Numbers follow operands without a space.

Braille
Braille (Pronounced: ) is a tactile writing system used by people who are visually impaired, including people who are blind, deafblind or who have low vision. It can be read either on embossed paper or by using refreshable braille displays that connect to computers and smartphone devices. Braille can be written using a slate and stylus, a braille writer, an electronic braille notetaker or with the use of a computer connected to a braille embosser. Braille is named after its creator, Louis Braille, a Frenchman who lost his sight as a result of a childhood accident. In 1824, at the age of fifteen, he developed the braille code based on the French alphabet as an improvement on night writing. He published his system, which subsequently included musical notation, in 1829. The second revision, published in 1837, was the first binary form of writing developed in the modern era. Braille characters are formed using a combination of six raised dots arranged in a 3 × 2 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
English Braille
English Braille, also known as ''Grade 2 Braille'', is the braille alphabet used for English. It consists of around 250 letters ( phonograms), numerals, punctuation, formatting marks, contractions, and abbreviations ( logograms). Some English Braille letters, such as , correspond to more than one letter in print. There are three levels of complexity in English Braille. Grade 1 is a nearly one-to-one transcription of printed English and is restricted to basic literacy. Grade 2, which is nearly universal beyond basic literacy materials, abandons one-to-one transcription in many places (such as the letter ) and adds hundreds of abbreviations and contractions. Both Grade 1 and Grade 2 have been standardized. "Grade 3" is any of various personal shorthands that are almost never found in publications. Most of this article describes the 1994 American edition of Grade 2 Braille, which is largely equivalent to British Grade 2 Braille. Some of the differences with Unified English Br ...

Persian Alphabet
The Persian alphabet ( fa, الفبای فارسی, Alefbâye Fârsi) is a writing system that is a version of the Arabic script used for the Persian language spoken in Iran ( Western Persian) and Afghanistan (Dari Persian) since the 7th century after the Muslim conquest of Persia. The Persian dialect spoken in Tajikistan (Tajiki Persian) is written in the Tajik alphabet, a modified version of the Cyrillic alphabet which has been in use since the Soviet era. The Persian alphabet is directly derived and developed from the Arabic alphabet. After the Muslim conquest of Persia and the fall of the Sasanian Empire in the 7th century, Arabic became the language of government and especially religion in Persia for two centuries. The replacement of the Pahlavi scripts with the Persian alphabet to write the Persian language was done by the Saffarid dynasty and Samanid dynasty in 9th-century Greater Khorasan. The script is mostly but not exclusively right-to-left; mathematical expressi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arabic Braille
Arabic Braille ( ar, بِرَيْل الْعَرَبِيَّة, ') is the braille alphabet for the Arabic language. It descends from a braille alphabet brought to Egypt by an English missionary prior to 1878, so the letter assignments generally correspond to English Braille and to the same romanization as in other braille systems, like Greek and Russian. However, there were once multiple standards, some of which (such as Algerian Braille) were unrelated to Coptic Braille. A unified Arabic Braille was adopted in the 1950s as part of the move toward international braille, and it is the standard throughout the Arab world. Other Arabic-based alphabets have braille systems similar to Arabic Braille, such as Urdu and Persian Braille, but differ in some letter and diacritic assignments. Arabic Braille is read from left to right, following the international convention. Numbers are also left to right, as in printed Arabic.

Kāf
Kaph (also spelled kaf) is the eleventh letter of the Semitic abjads, including Phoenician kāp , Hebrew kāf , Aramaic kāp , Syriac kāp̄ , and Arabic kāf (in abjadi order). The Phoenician letter gave rise to the Greek kappa (Κ), Latin K, and Cyrillic К. Origin of kaph Kaph is thought to be derived from a pictogram of a hand (in both modern Arabic and modern Hebrew, kaph כף means "palm" or "grip"), though in Arabic the ''a'' in the name of the letter (كاف) is pronounced longer than the ''a'' in the word meaning "palm" (كَف). D46 Hebrew kaf Hebrew spelling: Hebrew pronunciation The letter kaf is one of the six letters that can receive a dagesh kal. The other five are bet, gimel, daleth, pe, and tav (see Hebrew alphabet for more about these letters). There are two orthographic variants of this letter that alter the pronunciation: Kaf with the dagesh When the kaph has a "dot" in its center, known as a dagesh, it represents a voiceless vela ...

−
The plus and minus signs, and , are mathematical symbols used to represent the notions of positive and negative, respectively. In addition, represents the operation of addition, which results in a sum, while represents subtraction, resulting in a difference. Their use has been extended to many other meanings, more or less analogous. ''Plus'' and ''minus'' are Latin terms meaning "more" and "less", respectively. History Though the signs now seem as familiar as the alphabet or the Hindu-Arabic numerals, they are not of great antiquity. The Egyptian hieroglyphic sign for addition, for example, resembled a pair of legs walking in the direction in which the text was written ( Egyptian could be written either from right to left or left to right), with the reverse sign indicating subtraction: Nicole Oresme's manuscripts from the 14th century show what may be one of the earliest uses of as a sign for plus. In early 15th century Europe, the letters "P" and "M" were generall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tajik Braille
Russian Braille is the braille alphabet of the Russian language. With suitable extensions, it is used for languages of neighboring countries that are written in Cyrillic in print, such as Ukrainian and Mongolian. It is based on the Latin transliteration of Cyrillic, with additional letters assigned idiosyncratically. In Russian, it is known as (, 'Braille Script'). Alphabet The Russian Braille alphabet is as follows:http://specposobie.narod.ru/brail/ The adaptation of ''q'' to ''ч'' and ''x'' to ''щ'' is reminiscent of the adaptation in Chinese pinyin of ''q'' to and ''x'' to . Contractions are not used. Obsolete letters The pre-Revolutionary alphabet, reproduced at right from an old encyclopedia, includes several letters which have since been dropped. In addition, the letter э is shown with a slightly different form. Although obsolete in Russian Braille, these letters continue in several derivative alphabets.
