Abstract In this paper, we provide a formal explanation of symbolic execution in terms transition system and prove its correctness completeness with respect to an operational semantics which models the on concrete values.We first introduce formalmodel for basic programming languagewith statically fixed number variables. This model is extended language recursive procedures are called by call-by-...

HIGHLIGHTS We test whether symbolic number comparison is handled by an analog noisy system.Analog system model has systematic biases in describing symbolic number comparison.This suggests that symbolic and non-symbolic numbers are processed by different systems. Dominant numerical cognition models suppose that both symbolic and non-symbolic numbers are processed by the Analog Number System (ANS...

Fifty-three students, aged 11-13 years old, 29 boys and 24 girls, from three classes in the same Swedis...
