I encourage anyone who wishes to play with this slide rule to read the original patent first.
It is pretty dense material; the inventor was trying to cram a lot of information into a reasonably concise document. I use a simplified version of the algorithm he uses for computation; I am leaving out details that may be quite important.
Problem 1 : Solve 95 x 7.5 ( not using the vernier )
Problem 2 : Solve 9.504 x 7.512 x 0.8701 (chain multiplication using vernier)
Problem 3 : Find the logarithm of 5. ( work with the log scale)
