English Learners in the Mathematics Classroom. However, if you are up for it, this book will take you deeper and further into the theory and practise of hand computation than any other that I have seen. After a brief review of logarithms, this chapter discusses general approximation techniques for common and natural logarithms that are suitable for mental calculation, then details more accurate relations involving neighboring and intermediate values, offers methods for the more difficult problem of finding inverse logarithms, and concludes with doerfleg example of using logarithms and inverses to find higher-order roots of numbers.
Finding Rational Approximations to Precomputed Constants Often we encounter multi-digit numbers, such as scaling factors, that are difficult to use directly as a divisor or multiplier because of the number of digits involved.
The info was too complicated for me to understand or utilize. There are discussion boards devoted to: Continue with Facebook Continue with Twitter. This appendix describes the general procedure using continued fractions for generating whole-number fractions that approximate multi-digit numbers to a required accuracy and in practice involve multiplication and division by reasonably small whole numbers.
