Journal of Child Psychology and Psychiatry, 1995
Abstract The development of children's understanding of mathematical relations and of their grasp of the number system is described. It is discussed that children easily recognise one‐way pan‐pan relations but that the number system at first causes them difficulty.

Arithmetic norms and bounds of the arithmetic AN codes
IEEE Transactions on Information Theory, 1970Properties of integers, related to the generation of the arithmetic AN codes, are investigated in this paper. A programmable algorithm for the computation of the binary norm of an arbitrary integer is developed. A table of norms of the natural numbers is generated and from this the distribution of integers of a given norm is found.

The arithmetic of cuts in models of arithmetic
Mathematical Logic Quarterly, 2013We present a number of results on the structure of initial segments of models of Peano arithmetic with the arithmetic operations of addition, subtraction, multiplication, division, exponentiation and logarithm. Each of the binary operations introduced is defined in two dual ways, often with quite different results, and we attempt to systematise the ...

Arithmetic Theory of Arithmetic Surfaces
The Annals of Mathematics, 1989is a proper smooth surface over a finite field F,. The primary purpose of this paper is to develop arithmetic theory of the Brauer group Br(K) of K. Here we have to assume that the ring J(X, (x) of the regular functions on X has no embedding into R. In general all results hold true modulo 2-torsion.

Additive Arithmetic Functions on Arithmetic Progressions
Proceedings of the London Mathematical Society, 1987For an additive arithmetic function f, and positive integer D, let E(x,D) be \[ \max_{y\leq x}\max_{(r,D)=1}| \sum_{n\leq y,\quad n\equiv r (mod D)}f(n)-(1/\phi (D))\sum_{n\leq y,\quad (n,D)=1}f(n)|. \] Strengthening results from Chapter 7 of his monograph ''Arithmetic functions and integer products'' (1985; Zbl 0559.10032), the author proves that for ...
