My first go-around at a Q&A. Thank you to those who have left questions and comments. So let's get started:

Q:

Pierre Goasguen:

Hello Eddie ! I have known your blog because I bought a HP-Prime essentially for my pleasure, not for studies or engineer work. In France, during the 80', there was big interest for calculators like Ti57/8/9, HP , etc... And... I bought this hp-prime to know how calculator is now. And your posts are very interesting to learn about it. So, I hope that you continue to post algorithms, comments, etc. I like very much this. Thank's a lot Eddie.

A:

Pierre, thank you very much and yes, I do plan to continue to post algorithms. I find a of joy working with calculators and creating algorithms.

Hi Eddie, you have an awesome blog. I found it about 6 months ago and have been a regular visitor ever since. Do you have any plans/desires to some more advanced HP Prime tutorials?

A:

Road, thank you for the suggestion, it sounds like a great idea. I am working on a tutorial series for the Spreadsheet App which I plan to start posting by early October. If you have any specific suggestions, feel free to comment.

Eddie,

I have so many questions, but I'll hold down to just a few:

What are your favorite calculators and what makes them special to you?

How many calculators do you own and have you got a preference for machines from a particular era?

A:

Currently, my favorite calculators are the HP Prime and TI-84 Plus CE. The HP Prime because it has a little bit of everything: graphing, CAS, a touch screen, rechargeable battery, and the ability to work in full color. The TI-84 Plus CE because of its ease of use, rechargeable battery, and at least in the United States, almost everyone has some version of a TI-84. I also like TI’s connectivity software.

My favorite collectible calculator is the HP 42S. I traded one of my HP 50g calculators with a good friend.

At last count I have close to 110 calculators, the latest being a TI-34 II that I bought from a local swap meet a few weeks ago. I have been collecting calculators since 1990 (7th/8th grade). I don’t have a lot of 1970's calculators but sometimes I wish I was college age during that time instead of a newborn. The other era, I would have to say now. The ability of calculators grew over the last four decades. One positive of the smart phone/tablet is that more people are participating in creating calculator apps.

Q:

Kleo S:

Hi Eddie, your blog is awesome. I visit your blog almost everyday since 2013. I have bought TI-84 CE-T a month ago and I found it lacks the "product" function (I do not understand why, especially when the summation is available). I decided to create a small program, unfortunately I am familiar with Casio calcs and not with TI. Can you help me with this?

For Casio and i/3 the program is:

SetDecimal

ClrText

1->pr

Input b

For 1->i To b Step 1

pr*i/3->pr

Next

Print pr

A:

Kleo, of the top of the head, the program on the TI-84 would probably look like this:

: ClrHome

: 1 → P

: Input B

: For(I,1,B) (the fourth argument of For is step, but the default is 1)

: P*I/3→P

: End (End is the global “end” marker for loops on the TI-84.)

: Disp P

* The TI-84 doesn’t have an exact/approximate mode, but has a convert to fraction function. (>Frac)

Q:

Harry Pandolfino:

You should publish your comments, reviews and programs in an ebook. You make playing with calculators fun.

A:

Harry, thank you so much! I have so much fun with calculators and glad to see others enjoy them too. I am considering writing an ebook; it is a matter of fitting this in the schedule.

Thank you everyone. Let's do this again sometime!

Eddie
