George Brown (1650–1730) was a Scottish arithmetician, and inventor of two incomplete mechanical calculating machines now kept at the National Museum of Scotland.
In 1698 he was granted a patent for his mechanical calculating device.
He invented a method of teaching the simple rules of arithmetic, which he explained in his Rotula Arithmetica, 1700.
He wrote other arithmetical works; the last of them, Arithmetica Infinita, was endorsed by John Keill.
