Editing Atanasoff–Berry computer (section)

==Function==
The ABC was designed for a specific purpose{{snd}} the solution of systems of simultaneous linear equations. It could handle systems with up to 29 equations, a difficult problem for the time. Problems of this scale were becoming common in physics, the department in which John Atanasoff worked. The machine could be fed two linear equations with up to 29 variables and a constant term and eliminate one of the variables. This process would be repeated manually for each of the equations, which would result in a system of equations with one fewer variable. Then the whole process would be repeated to eliminate another variable.

[[George W. Snedecor]], the head of Iowa State's Statistics Department, was very likely the first user of an electronic digital computer to solve real-world mathematics problems. He submitted many of these problems to Atanasoff.<ref>{{cite book |first=Raúl |last=Rojas |title=The First Computers: History and Architectures |publisher=MIT Press |year=2002 |isbn=0-262-68137-4 |page=102 |url=https://books.google.com/books?id=nDWPW9uwZPAC }}</ref>
