WebThis method is particularly suitable for manual conversion from an arbitrary radix r to radix 10, given the relative ease with which we can perform radix-10 arithmetic. To perform the radix conversion using arithmetic in the old radix r, we repeatedly divide the number x by the new radix R, keeping track of the remainder in each step.

WebMethod 1: 97 is the same as (100 − 3), so you can think of the calculation as 7 × (100-3) This is the same as (7 × 100) – (7 × 3) Now you have replaced the difficult multiplication with two simple multiplications and a subtraction: 7 × 100 = 700 7 × 3 = 21 700 – 21 = 700 – 20 – 1 = 679. Therefore 97 × 7 = 679. Method 2:

The Trachtenberg system is a system of rapid mental calculation. The system consists of a number of readily memorized operations that allow one to perform arithmetic computations very quickly.
