(This is not true. Please take a good look though. 1. History of arithmetic operations Appearance of the + sign In the thirteenth century, Leonardo Pisano (Italian mathematician) wrote 7 plus 8 as '7 and 8' The word 'et' is written as et, which is reduced to create the symbol of +. - Appearance of symbols In 1489, Beadman (mathematician of Germany) stands for minus, the Latin word for "short of" It was born because it was used only after. The appearance of the x symbol The first person to use it is the British Walrus Autret, I do not know the origin of the loss. ÷ Appearance of symbol This symbol has been around for a long time, and in the mathematics books of the 10th century, I wrote the word 'break' together, but it removed the letter 'break' and was written only as ÷ All. The appearance of = sign It was originally written in the book "The Whetstone of Wisdom" written by the R Record (1510-1558) in 1557, Ya was longer than we are now using. 2. Diopantos introducing symbols into Greek mathematics In the mid-third century, Alexandria's Diophantos (200? ~ 284?) Was the first of Greek mathematics He was a mathematician, bishop, and writer who introduced the symbol. Diopantos is the Greek mathematician I am a mathematician who introduced an elderly symbol. In a mathematics magazine published in the 11th century, He is a bishop of Van Alexandria and is described as a professor of mathematics and a writer. Diopantos is the great mathematicians of Greece, Archimedes, Apol45rummy.comlonius, Ptolemy, Heron, Nicomacus, and others. The development of mathematics can be divided into three stages according to the narrative form. First, The second, the step of shortening by omission, and the third is the stage of symbolization. Rhetorical A step is a step of expressing an expression with a sentence. Diopantos is a simplification of the equation in which rhetorical expression has been used for centuries. To create your own notation. However, despite his ease, his ID The language was not accepted in Greece and developed by the Arabs. In the sixteenth century The notation of Lerodiopanthus is translated into Latin and has a strong influence on European mathematicians And played a significant role in the development of algebra. He has put algebra into settlement, and his most famous book, "Surlyn" It is likened to the "geometric principle" of De. At that time Diopantos solved the equation Because I thought that I limited it to the rational number, I thought. Today, the equation for obtaining the integer solution is called the diopanet's equation. That's why I call it. ---- Developer contact: Busan Metropolitan City Centum Dong 51-203 (Udong, Checkdog Building) Version history 너도나도 암산왕! 풀어라!
