MATH-MATIC

Designed by: Remington Rand

MATH-MATIC is the marketing name for the AT-3 (Algebraic Translator 3) compiler, an early programming language for the UNIVAC I and UNIVAC II.

MATH-MATIC was written beginning around 1955 by a team led by Charles Katz under the direction of Grace Hopper.

A preliminary manual was produced in 1957 and a final manual the following year.

Syntactically, MATH-MATIC was similar to Univac’s contemporaneous business-oriented language, FLOW-MATIC, differing in providing algebraic-style expressions and floating-point arithmetic, and arrays rather than record structures.
