Over the 5 years I used a HP 32SII and found that the RPN is more efficent when doing simple or complex problems.
This is an oustanding product, i agree !!! I have the original manual and the protection cover since 1993. It had never broke down, i just replace the batteries some times (not often), that all, and i use it everyday, always in my bag when i teach. I had bought the HP32SII in a mall, just to have one in USA, and never though it will be there with me 15 years after. I have never bought another calculator since 1993 !!!!! I brought this calculator in 1993 in the USA !! i am french and leave in France.
I was reading all your reviews here, and i agree with the positive reviews. RPN is really powerfull, and you make never mistakes with it.īut with algebric calculators, all the time you do not know the order of the execution of the different terms of your calculation, and you have no intermediate calculations (except for the HP 27s) I have finished my studies, thus I have given my HP 48 to a friend and I have came back a HP 32 s II and I do not regret my choice! I love HP 48, HP42 and HP 32, but the HP 48 is too big, too complex, and too heavy, too "theoretical", but really good for students, and HP 42 is now not available. I have tried a lot of calculators, and in my opinions HP RPN calculators are the best, and its HP 32s is the best calculator of the world!
The calculator runs on three LR44 batteries, which come with the unit. The LCD can display one line with 12 characters and is bright enough for most environments. And, like most scientific calculators, the HP32SII can perform decimal/hour/minute/second conversions, polar/rectangular/angle conversions, unit conversions, base conversions, and arithmetic. We like Hewlett-Packard's HP Solve feature, which lets you solve for any variable without having to rewrite your equation. With 384 bytes of memory, 26 variable keys, more than 100 built-in scientific and mathematical functions, and RPN data entry, you'll find everything you need for efficient and fast calculating in this compact unit. Calling all engineers-Hewlett-Packard's HP32SII Scientific Calculator is the calculator for you.
