ARITH-MATIC is an extension of Grace Hopper's A-2 programming language, developed around 1955. ARITH-MATIC was originally known as A-3, but was renamed by the marketing department of Remington Rand UNIVAC.
<!--How was A-2 extended?. Answer: I found in the book of Sammet, page 132, this words: 'A-3 (also called ARITH-MATIC) was an improvement of, but not completely compatible with, A-2. It also provided a number of additional facilities which were not in A-2"
