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. :)

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:

It could! Some of us used Texas TI-51. So there, HP-freak :-) ...

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[^]

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!
- I would love to change the world, but they won’t give me the source code.
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!

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.

Blimey, I have an almost exact 'clone' of that rule made by Faber Castell - it's the one I used through 6th Form and most of Uni...

I found one of my old slide rules a few months ago. I couldn't remember how to use it :sigh:
I wanna be a eunuchs developer! Pass me a bread knife!
I had a circular slide rule - fitted neatly in the inside pocket and was easier to use than a linear 6" rule.

I saw those in the uni shop and was tempted, but I was on student money and had to pinch pennies. But when you can buy a boxload without feeling it, you don't need them any more :(

That is a lot of reading. Where is the 30 second YouTube video? ;P

HP calculators were (are?) also RPN.

If you are helping your children with math you have not seen in 20+ years, I found Alpha Wolfram (free edition) incredibly helpful. On some problems, the free version would not show all of the intermediate steps, but you could at least find the correct answer.

Now that you mention it, at the time when I had that Omron (around 1980), there was one HP model around that at least one of the other students used. But most were using TI caluclators with direct input and brackets. I believe RPN was all but forgotten by the time I went to university (1984). That's when I got my first programmable pocket calculator, with a whopping 10 KB memory (quite a lot when you take into consideration this was still the high time of the 8 bit home computers)

It didn't take long to get used to RPN, and then I hated other calculators. What's with these stupid parentheses buttons?! And the first time I saw a parser and stack for interpreting arithmetic expressions in Comp Sci class, it was like deja vu.

Does anyone remember the Forth programming language? (The top leader even presribed it, and the operations: Go Forth, and multipy.) It was stack based: You pushed two numbers on the stack, executed a multiply, and the two top stack entries were replaced by their product. I was working for a company that developed (a few) commercial applications in Forth. The guys in that team were incapable of using TI calculators, they were dependent on HP models.

I had to learn both systems since I helped my friends with math, and they all used TIs. :^)
