Comment Some math required, but not calculus (Score 1) 583
Long ago only math majors could get close to the vacuum tube monster computers (late 50's). Knowledge of different bases (10, 2, 8, 16, 12, 60) were necessary. Also knowledge of rings, fields, boolean, and other modern algebras were essential. I hated calculus and took any math class that did not require calculus. My degree was math (1961) and I was in the computer industry for over 50 years and I never, ever had to use calculus.
