How does it work?

log(ab) = log(a) + log(b).
log(1a) = log(a) = log(1) + log(a).

Now you can see how the distance computer is laid out.

Solving a step-distance problem.

D = NL,
log(D) = log(N) + log(L)
Workings of the distance computer


If you have enjoyed learning about the secrets of the distance computer, think about taking more math courses in high school.  The logarithm function is usually studied in "Algebra 2."  There are many other wonderful things that you will learn in Geometry, Trigonometry, and even Calculus.  In Physics, Chemistry, and Biology, you will learn how the mathematics works to produce the world around you.  You have started on a great adventure.  Good luck!
