Modern electronic calculators are small, digital, and usually inexpensive devices to perform the basic operations of arithmetic. Before we had calculators we had slide rules. In 1632, the circular and rectangular sliderule was invented by W. Oughtred. In 1885, Burroughs filed his first patent for a calculating machine. However, his 1892 patent was for an improved calculating machine with an added printer. William Seward Burroughs invented the first practical adding and listing machine.
