easy_multplication.py contains a function which finds multiplication of two numbers using a digit by digit mulitplication (single digit multiplication) of a multiplier. Again the multiplier will be decided based on the number of digits of both numbers, the number with less digits will be selected as multiplier. This method works better when we d…
