Question about Texas Instruments TI-83 Plus Calculator

Ok, if your trying to do something like this: 2+2=4 then make it continue adding by 2's (6,8,10...)

What you do is after you type 2+2 and press enter, you need to press the "+" and u should see it show this "ans+" then type 2. Then this should continue adding by 2's. Hope this helped.

On any calculator, let's convert degrees-minutes-second to degrees and then we will do the reverse.

Let's start with the number of seconds in a minute - 60, so we must take the seconds and divide by 60 to get the number of minutes. Next, add the number of minutes. The number of minutes in a degree is 60, so we take this total and divide by 60. Now we add the number of degrees to get out final answer.

Example: 35 degrees 50 minutes 32 seconds

(32/60 + 50)/60 + 35 = 35.842222 degrees

Just out of interest, let's start with 35.842222 degrees and convert it to degrees-minutes-seconds. We know it is 35 degrees, the whole number. Now we have to determine the minutes and seconds. Start by subtracting 35 to get the decimal 0.842222. Now multiply by 60 to get the number of minutes. I get 50.5332. Subtract 50 from this and multiply again by 60. I get 31.9992, which rounds to 32 seconds.

Good luck.

Use the (-) key to the right of the decimal point key when entering a negative number. The - key to the right of the 6 key is for subtracting something from something else. In order to subtract from something, if you don't specify anything then the calculator uses the previous answer as designated by "Ans." The same thing happens with the + key for example, because it adds something to something else.

Minus and change-sign are two completely different things. Minus is used to subtract one number from another. When you press minus when the input line is empty, your telling the calculator to subtract. The only way it can subtract the number you're about to put in is to subtract it from something else, and that something else is the previous answer, hence the "Ans."

If you want to input a negative number, use the change-sign key. If you want to subtract one number from another number, use the minus key.

Try pressing the plus key when the input line is empty. You'll get Ans+ in this case as well, The same with multiply and divide, among others, and for the same reason.

I love that old, little calculator, the TI-1795+ (not the new one, SV).

Does anyone know where to get any more of these. I'd buy a few,

but they are probably out of production. I've had my three for years

and years and years. They still work fine.
