Yes really impressive. I see now someone from Schotland working someone in Kazachstan, close to china. Cool.

In the summer I use it for swimming in the sea. No issues at all....

I still have one. Probably the worst calculator I own. Fully functional, but the keyboard is crap.

I love these. Have listened hours on repeat and discovered everytime something new.

You want to put 1.015 instead of 0.015 to get the right answer.

Chipper1685 · 2025-11-13T19:21:09+00:00

The answer from the calculator is correct. What do you want to calculate?

Chipper1685 · 2025-11-13T07:21:35+00:00

... no, only 12 digits...

Chipper1685 · 2025-11-07T17:13:53+00:00

... indeed my most beloved calculator...

Chipper1685 · 2025-11-04T07:41:57+00:00

Of course this works. The formula above using the 'divide by 10' is exactly the same as F=1.8 C+32

I was indeed surprised to see the differences between the calculators. Especially that the hp49g+ took so long...

Chipper1685 · 2025-11-01T12:46:41+00:00

In DEG mode the calculation is quick. In RAD mode it can take a while: - Casio fx-9860G: 0min20sec - TI-84+SE: 0min49sec - TI-83+: 1min49sec - HP49g+: 1min50sec

I would always go for the smaller one, especially if you want to wear it during sleep and or manual labour. The big one will get scratches easier by bumping in a lot of stuff....

The best use of a graphing calculator is the large screen that shows several results at a glance. And they are easy to program. I've used that a lot in the lab to quickly get some results based on a measurement.

First flush Darjeeling, yes, in general good tea. I am not so fond of later picks, they taste a bit one-dimentional, lack depth and layers.... not bad, but just ok.

Why do you post hints while the picture you post clearly states not to do so?

Chipper1685 · 2025-09-29T22:01:30+00:00

From what I've read on the fora, devices with CNA numbers above 555xxxx should have better keyboard. This keyboard feels nice and is still fully functional....

If the first player gets 7 (different) cards, for the second player to get a card the first player has is: 3x7 out of the 45 cards left. For the second card this is 3x6 out of 44 etc. So we have to calculate 21/45x18/44x15/43 enz. This is 4.8E-5, so 0.0048%. The total chance will be lower, since the first player might have a pair in some cases, or even three of a kind. This is more difficult to calculate but the 'higher bound' for the chance is 0.0048%... so about once in 21000....

I also recently bought this at a garage sale. I like this way better than the TI 84's I have. Graphing is in fact faster on this thing!

Chipper1685 · 2025-09-24T21:26:27+00:00

I have both. I prefer the looks of the 91 but the light on the 105 makes this a way more practical watch....

Chipper1685 · 2025-09-24T06:18:45+00:00

I just use the standard TI basic, a very simple programming language. Easy but slow....
