1. Did you have grandkid show you that trick?

I need to borrow a kid.

3. Usually it would be a grandkid but this time it was my husband.

I was impressed.

2. I knew about that but that's way more math than I ever need,

so I never turn the calculator app sideways. It just confuses me.

4. EE, that is Rad.

tanh you!

[Bristlecone]

5. If you turn it completely upside down, it becomes an abacus

Super handy.

8. Still not in RPN

For the real eggheads out there.

I have add-on apps that mimic a real HP RPN calculator. I am paralyzed without them.

Once you go RPN, you never go back.

9. How long will it take people to realize that one should turn the phone sideways to shoot video?

I stand firmly against vertical video!

10. That is very nice, but I was hoping ...

... that if you turned it sideways the other way, it would be a hexadecimal calculator.

Oh well.
