I am a mathematics instructor helping a student with a calculator problem. The calculator reports an overflow message for values it should be able to calculate. I know the calculator reports this message when the value of the number has more digits than is allowed for the given mode.

I am calculating an easy compound interest problem in one-step:

1000(1+.08/365)^(365*3)

I use my older TI-83 and get the approximate answer 1271.21. I know this calculator should be able to evaluate this expression. Is this a fixable hardware problem or has TI announced anything lately about a repair? This is a brand new calculator and I have reset all of the original settings.

Thanks.

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of.(from cars to computers, handyman, and even drones)

click here to download the app (for users in the US for now) and get all the help you need.

Goodluck!

You may get**
Memory Error** when you try to access an archived variables. From the other hand
**Memory Error** message is displayed if there is not enough free RAM to access the
archived variables. For correcting **Memory Error** message use the **2ND** then **MEM** to check RAM free size and **2ND** then
**VAR-LINK** to determine the size of the archived variables that you want to
access. As the third step for correcting this problem deleting unnecessary variable
from RAM and archiving large variables or programs. By the definition, the RAM
free size must be larger than the archived variables

I am aware that this does not fully answer your WHY question but it may help you decide what to do.

On the TI92 Plus, which has the latest OS for that machine 2.09 Advanced mathematics Software one gets the result Pi in EXACT or AUTO modes and 3.1415926536 in APPROXIMATE mode.

However when in EXACT/AUTO mode the calculator displays a warning message Memory Full, Simplification may Not Be Complete. (see screen capture.)

On the Voyage 200 PLT with OS version 3, the same as on the Titanium (not Platinum), I get an undefined result in EXACT MODE and 3.1415926536 in APPROXIMATE MODE.

So you can get the approximate value of the integral on the Titanium or the indefinite integral which you can evaluate between the two boundary points.

your model isn't listed, but read rules Calculators are only allowed to be used on the mathematics test; however, a calculator is not necessary to take the exam. Any student who attempts to use a calculator on the science exam will be dismissed and the worksheet will not be scored. It is the student's responsibility to make sure they bring sufficient batteries and that the calculator works properly. Test center personnel do not have backup calculators or batteries.
Only certain types of calculators may be used during the test. Most four-function, scientific or graphing calculators are permitted, but some features may have to be disabled before the calculator can be used. Devices that include calculators among their functions-cell phones, laptops, PDAs-are forbidden, as are calculators with built-in algebra capabilities or QWERTY keyboard buttons. Also, certain specific models of calculators are forbidden, including the following: all Texas Instruments model numbers that begin with TI-89 and TI-92, as well as the TI-Nspire CAS (the non-CAS TI-Nspire is allowed); the Hewlett-Packard hp 48GII model and all model numbers that begin with hp 40G, hp 49G, or hp 50G; the Casio Algebra fx 2.0, ClassPad 300, and all model numbers that begin with CFX-9970G; and all electronic writing pads or pen-input devices, except for the Sharp EL 9600.

As mentioned previously, certain calculators can be used after extra features are disabled. Calculators that use paper tape, for example, may be used after the tape roll is removed. If the student has a model that makes sounds, disabling the sound feature makes the calculator acceptable for use during the test. For calculators that can communicate wirelessly, infrared ports must be covered with opaque material (such as electrician's tape or duct tape) of sufficient thickness to block infrared signals; the Hewlett-Packard hp-38G and hp-48G series are examples of this device type. Also, calculators with power cords must have the cords removed before they can be used during the exam.

You can find the program editing menu under "Apps". Choose "New..." After you enter the name of your program, you will be able to edit it. To run it, go to the home screen (the screen where you enter mathematical equations), hit 'catalog', then 'f4', and choose the program from the list.

As for the coding itself, this site has a solid reference of many concepts and commands that are involved when programming for the TI-89: http://tibasicdev.wikidot.com/68k:home The best way to learn, however, is to play around and figure things out yourself. Programming for the TI-89 is much more powerful than it is for the previous TI calculators. Best of luck!

There are many reasons a calculator will report an error.

Simple calculators usually only report errors for math operations that are not possible such as dividing by zero or if you hit equals when there is no number between a math symbol ( 3 ++ 4 = ERROR)

For more complicated calculators like the TI-89 an error can come up due to such mathematical errors and there is a lot of room for error with more complicated equations. Also there are programs in the calculator that if not done correctly will crash and cause an error.

The instruction booklet should have a list of common errors and how to avoid them. Look at the table of contents or the index to find such a list.

Good Luck hope this helps.

The factorial of 120 is 6.6895029134491270575881180540904e+198

which is too big for most calculators to display, i.e. it is 199 digits long.

Yes, the Ti nspire not only functions as a ti83 but, also operate w/ nice advance math software that any teacher would envey. It comes with the ti83 keypad plus software and great instructions to help the instructor at all levels of math learning. I don't know any better and it is a beautiful plan that ti has set up.

I heard of instructor disabiling APPS but, not functions. One reason I can't see that is I can download a program that does the same thing and hide it w/ instructor even knowing its there unless he ran a search in ever folder or open a lot of programs

Mine is the same, I Called TI and they said they would replace the calculator for $75 if I sent the one I have in now even though it doesnt hava a warranty so the answer would be $75
