Slide Rule? Pah! When _we_ were kids there were no battery chargers for sliderules...

What about mental arithmetic?

0.2 x 0.5" and 40 connections, huh.

2 x 5 = 10. (0.1" grid)
4 x 10 = 40. ( 0.05" grid)

    Slip AND slide.
    
    My vintage Dietzgen, made of finest bamboo, steel, and dry lubricant, hangs
    framed behind glass on the wall in my home office. There, after yielding
    many a useful 3 sig-fig result in my college and early work career, it hangs
    as a proud reminder of past conquests. My children, on the other hand, refer
    to it as a relic of the past - much like the Beetles, the Stones, and Dad.
    
    Cheers,
    
    Dad (the bill payer)
