Ah, I got my first calculator toward the end of my first year I teaching (1974-75 school year), it was a Texas Instruments model that could add, substract, multiply and divide - with NO memory, if you needed it later you had better have written it down. It was a Father's Day present from my son, who wasn't born until the next December. My wife never did explain to me how that was possible.

Since I taught history and the history of science was a module in the World History course I kept a slide rule and would show it to my students, they were fascinated and in the early years some student would say "My Dad/Mom/Grandfather/Grandmother has one of those!"

When you are talking about sliding rules, that reminds me when I watch the video of the SR71 who was built with the same.
And a few years later they use a computer I believe to re-create the same work and the results were the same.

I believe the slide rule was the first calculator. Still pretty darned efficient, and fast.

Think I still have a slide rule somewhere. The first calculator I ever used was in a class in Jr. College. I think it was physics. It was mechanical and HUGE. It was about 3 feet square and tapered from the back to the front from about a foot at the back to about 6 inches deep in the front. Kind of looked like a bank's adding machine of the time (1965-1967) Some of the more affluent students had hand held ones, but they were large in comparison to now.

My slide rules have been lost in the rocks of time. The only one I have left is a tie clip, about 2" long. It works but the precision leaves something to be desired.

need to go back to school and learn this stuff This is some of what's being taught to your kids, etc. I'm sure when they graduate they will throw out the old math and use this in everyday living? Give me a break ! ! !

Say what you're gonna say, and don't send youtube stuff to say it for ya.

How'bout the merchant's math: 35x12 is the same as 12x35
10x35=350
2x35= 70
Total - 420. Done! It can easily be done in head...
