Texas Instruments. Easy to use INTERFACE on their TI-83 and up MODELS. (I own a 84+ Silver and a 89 Titanium)

I have a TI SR 50, somewhere. Haven't looked for it in years. Last time I tried it though, it still worked! The NiCad didn't hold a charge for very long
though, which is understandable.

As I recall, it cost $150 when I bought it.

Tell anyone to give you 5 consecutive #'s to add...
Take the middle # and multiply by 10...
Then DIVIDE in 1/2 and there's the answer.

Fun !Quote from: patio on September 27, 2007, 06:32:40 PM

Wouldn't that be the same as multiplying by 5?Yep ! Cool it actually works. I love it.

Think of any number between 2 and 10.

Okay now, mulitiply it by 9.

Now you should have a two-digit number. Add the two digits together.

Now add -1.

Now divide by 2.

Now take the square root.

You should end up with the number 2!the best calculator is your computer.Yeah but I need a portable graphing one. It looks like I'm gonna get a Texas Instruments.Quote from: Comp Guy on September 28, 2007, 11:01:45 PM

No, I end up with sqrt(4), which is +/- 2. Anyone fancy 7 million $

You got me! I should've know that since we were just TALKING about that in math class. Oh well, nobody's perfect.Quote from: RICHENSTONY on September 29, 2007, 06:02:52 AM
