There are many definitions of chaos, of which Devaney-chaos and pos itive topological entropy seem to be the strongest. Let A = [0, 1, . . ., p -1]. We define a continuous map on AZ using addition with a carry, in combination with the shift map. We show that this map gives rise to a dynamical system with positive entropy, which is also Devaney-chaotic: i.e., it is transitive, sensitive and has a dense set of periodic points. © 2019 Korean Mathematical Society.Discrete chaotic transitive positively expansive entropy
