The Texas Instruments TI-30X IIS 2-Line Scientific Calculator is perfect because
- It is scientific so it does just about everything you would ever want in addition to the basics so it includes
- A 2-line display
- Statistics on one and two variables
- Degrees, radians and grads
- Scientific and engineering notation
- Fractions
- Conversion
- Copy and paste with multiple storage cells
- It is little
- It has a sliding protective computer
- It works both off battery and solar energy
- It less than a new air filter
You can buy a science and math friendly calculator that costs next to nothing, can take anywhere without worrying about powering or dropping it, to easily work on just about any real word calculation that you find yourself doing every day.
This calculator rocks!
But no RPN, right?
No. Only HP calculators have RPN, right?
Did I mention that it works on solar and battery?! š
Yeah, I think you’re right.
I’ll be sticking with Android RpnCalc for now. Though I do love the idea of stand alone calculators…
Did I mention that it even comes with a slide-out case just like its big brothers?
RpncCalc sounds better.
If you did your math in Forth or a Scheme REPL then you would earn some kind of credits for that.
Thanks to your post, I did a fresh search for RPN Calculators on Google Play.
Here’s a very clean option: https://play.google.com/store/apps/details?id=com.anaoum.calculator – no ads, no scientific functions, just stack based math.
And here’s a comprehensive clone of the HP-42S: https://play.google.com/store/apps/details?id=com.thomasokken.free42 – again, no ads, high quality stuff.
Thanks for the inspiration.
You are welcome and thanks for sharing what you found. Cool!
