This study analyzed children's use of mental computation strategies and the standard algorithm on multi-digit subtractions. Fifty-eight Flemish 4th graders of varying mathematical achievement level ...

The Common Core State Standards teach students the algorithm for multi-digit addition and subtraction in 4th grade. But some experts say it should be taught sooner.

The present paper describes the success, the methods (mental, informal written, standard algorithm) and the strategies of informal written arithmetic to be observed when 300 elementary students worked ...

The Numerical Mathematics Consortium announced the latest revision to a technical specification, introduced earlier this year, that defines an open mathematics semantics standard for numerical ...

Focused on reducing the overall cost of numerical algorithm development and reuse in different disciplines, the Numerical Mathematics Consortium is committed to ensuring algorithm portability ...
