I started high school with a slide rule and finished with an HP-45 calculator. I didn't think it could get much better. :laugh:

What? Microsoft? I think I was in third grade when they started up.

I went through all school including high school equivalent with a book of log tables! No fancy slide-rule technology for me - never mind a calculator!

With a slide rule, anything after the third significant digit had to be figured out in your head, so log and trig tables were still needed if the answer had to be accurate. The HP-45 was still high-end at the time. The HP-65 (programmable) had just come out that year.

FWIW, the calc.exe version included in Windows 10 Insider builds has included a graphing calculator for a while now. I have no idea how it compares. Just thought I'd point it out. [Edit] Apple Store or Google Play only. Not in the MS store, which means no Windows version. We officially live in a different world. [Edit] Ok, I had only paid attention to the image with the graph, and I totally missed the rest of it. A solver seems a lot more interesting...

I found one of my old slide rules a few months ago. I couldn't remember how to use it :sigh:

I have a love for my TI-Nspire, but I like the guidance these types of calculators give. I recall a similar product by Wolfram being quite handy.

My brother-in-law - about ten years older than me - used to tell people that he was incapable of summing the grocery bill without having his slide rule available. That joke was surprisingly successful for quite a few years, especially with those my age and younger, who knew well what slide rules were, but never used them seriously, so we didn't know their application area, mathematically speaking. People his own age, who knew slide rules well, found the joke silly. Young people of today have no clue about what a slide rule is, so they never get the joke. But for ten, maybe twenty years, half of the audience would laugh and the other half would wonder: What's so funny?

That's definitely an "in" joke. Even when slide rules were used, not that many people had to use them. Maybe he used it as a litmus test to see who got it.

The point being that slide rules were not used for addition/subtraction - only for multiplication/division, power/root, exponential/log, and trigonometry.

High school was Sept 1980- June 1984 Chemistry in 1983 even though we had calculators the chemistry teachers required us to use slide rules. I got to use my Dad's, he was an electrical engineer, had to be VERY careful with it.

High school was Sept 1970 to June 1974. Chemistry was also where the slide rule or calculator got used the most. But slide rules weren't mandated and very few students used one. The HP-45 came out in 1973.

On the contrary, I'm happy this did not exist in school. Would have made us more dumb, don't you feel so? Yes, it would have reduced our effort in solving problems, but would not have developed our thinking faculties, and also problem solving abilities, isn't it?

You're quite right. Let me rephrase: I would have wished this had existed when I were in school. Because like everyone else (well, mostly) I'm a lazy bastard. But yes, it would have made made me more stupid, like the kids today. :)

In those times they were called 'Walkie Talkie'[^]. I liked that name - in fact I find it would fit mobiles today even better ;)
GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)

Same for me, only I ended up with a RPN[^] calculator, the Omron 12SR[^]

Me too! Started Uni with a double-scale slide rule, finished with some weird 12 digit calculator which only had a 6 digit display!. Went all the way through school (until my last year) using my father's old 7 figure log tables. Still got them: showed them to a class of 14 year old IT students recently - they'd never even heard of them!
