Math the Easy Way (1960's)?

[Dibbons]

When I was youngster, my uncle tried to introduce me to the benefits of using a slide rule. I was immediately overwhelmed and confused by the brief "lesson".

I think of all the cool stuff the Chrysler engineers cooked up by using those things

I always thought they were cool...and have one but haven't tried to use it since the '70's.
I like this version too:

I learned how to do calcs with a manual flight computer E6B. Tough to use while you’re PIC.

We went to the moon with a slide ruler and a pencil. Go figure.

I learned how to do calcs with a manual flight computer E6B.

Oh yeah, I learned how to count to 20 & 3/8 when I was naked.

I found my old flight bag recently. Inside was the old "whiz wheel".

I still have one of those "whiz wheels" (somewhere), but I'm sure I forgot how to use it.

Same here...only difference is, I NEVER did know how to use it.

I used a Slide Rule when doing Weight and Balance for aircraft in the 80's before they gave us computers to do it. Still have mine from my C-130A days too. Still the best math tool is my good ol' Brain Bucket...cr8crshr/Bill

But how'd you come up with 3/8 when you were counting in millimeters?
