摘要：The present paper provides a state-of-the-art overview concerning the role of working memory in carry and borrow operations in mental arithmetic. The role of the executive working-memory component is discussed, alongside the contribution of the phonological and visuo-spatial working-memory components. Moreover, a broad view on various carry characteristics (such as the number of carry/borrow operations and the value of the carry) and various operations (addition, subtraction, and multiplication) is provided. Finally, some ideas for further research are offered.
