MATHEMATICS AND MENTAL CALCULUS
Journal Title: Journal of Science And Arts - Year 2010, Vol 12, Issue 1
Abstract
This paper presents some great skills of both mathematicians and nonmathematicians in mental calculus. These information are important because the personalities we spoke about were very significant for their times and their work meant a lot for the progress of the mathematical science.
