As we all know fibonacci number goes something like this,
1,1,2,3,5,8,13,21,34 ...blah blah blah.
One of the area of application is convert km to miles and vice versa. If you want to
a) km to miles = read from left to right
b) miles to km = read from right to left
It work except for 1. :) Cuz 1 miles is 0.6 km. Close enuff tho if we apply rounding rules.
