Abstract

Previously, in [Bergstra and Tucker 2023], we provided a systematic description of elementaryarithmetic concerning addition, multiplication, subtraction and division as it is practiced.Called the naive fracterm calculus, it captured a consensus on what ideas and options were widelyaccepted, rejected...
