# Where was sign language invented?

One of the earliest written records of a signed language occurred in the fifth century BC, in Plato's Cratylus, where Socrates says: "If we hadn't a voice or a tongue, and wanted to express things to one another, wouldn't we try to make signs by moving our hands, head, and the rest of our body, just… as dumb people do at present?" In 2nd-century Judea, the recording in the Mishnah tractate Gittin said that "A deaf-mute can hold a conversation by means of gestures. Sign languages have often evolved around schools for deaf students. In 1755, AbbÃƒÂ© de l'ÃƒÂ‰pÃƒÂ©e founded the first school for deaf children in Paris; Laurent Clerc was arguably its most famous graduate. Clerc went to the United States with Thomas Hopkins Gallaudet to found the American School for the Deaf in Hartford, Connecticut, in 1817. Gallaudet's son, Edward Miner Gallaudet founded a school for the deaf in 1857 in Washington, D.C., which in 1864 became the National Deaf-Mute College. Now called Gallaudet University, it is still the only liberal arts university for deaf people in the world. American Sign Language (ASL), used in the US and most parts of Canada, is derived from French Sign Language whereas the other three countries sign dialects of British, Australian and New Zealand Sign Language. Similarly, the sign languages of Spain and Mexico are very different, despite Spanish being the national language in each country, and the sign language used in Bolivia is based on ASL rather than any sign language that is used in a Spanish-speaking country. International Sign, formerly known as Gestuno, is used mainly at international Deaf events (MORE)

# What is the sign for multiplication and addition?

If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative. Multiplying a positive number by a negative number, or a negative number by a positive number, results in a negative result.\n\n.
For addition, if you add two positive numbers, the resul…t is positive. If you add two negative numbers, the result is negative. If you add a positive and a negative number, the result depends on which of the numbers has the greater absolute value. For example, if the positive number has the greater absolute value (distance from zero), the result will be positive. If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative. Multiplying a positive number by a negative number, or a negative number by a positive number, results in a negative result.\n\n.

# Does the addition of the 13th zodiac really changed your zodiac sign?

You're probably thinking of the supposed addition of Ophiuchus, the Snake-Handler, as a "new" sign of the Zodiac. Ophiuchus is not part of the traditional Zodiac, which has twelve signs (corresponding to the twelve New Moons (or Full Moons) in a year. These were marked out and named after the twelve… constellations along the line of the apparent path the Sun, Moon and planets (the ecliptic). In one sector of the sky, there are Ophiuchus and Scorpio. Ophiuchus is a fairly faint constellation, while Scorpio is very prominent constellation (in fact, one of the only ones that is even recognizable as what it is said to be). A lot of Scorpio's stars lie well to the south of the ecliptic, but that didn't matter to the astrologers -- they called that sector of the sky after the dominant constellation. And the Moon goes quite a long way north and south of the ecliptic anyway, so the Zodiac is more of a band than a line. Astronomers are a little more fussy and they have established very fixed, rectilinear boundaries between the constellations, and, according to their reckoning, a segment of the ecliptic line passes through the area they label Ophiuchus. (And very little of the ecliptic line passes through Scorpio.) However, the band of the ecliptic is a different matter, and anyway the astronomers' boundaries are completely irrelevant to astrologers; on top of which, most western astrologers don't even use a form of the Zodiac that lines up with the constellations. .
