2744	 Addition in an Arbitrary Base Without Radix Conversion	 This paper presents a generalization of an old programming technique using it one may add and subtract numbers represented in any radix including a mixed radix and stored one digit per byte in bytes of sufficient size. Radix conversion is unnecessary no looping is required and numbers may even be stored in a display I O format. Applications to Cobol MIX and hexadecimal sums are discussed. addition subtraction decimal arithmetic arbitrary radix arithmetic radix conversion MIX arithmetic Cobol display arithmetic mixed radix arithmetic
