I have the exact same problem (just happended recently) with my TI-5045 II after 25 years of good service. My solution? I just bought another model: Sharp EL-1801V at Stapels for about $31.00. To get the old one fixed will probably cost me $25.00-30.00 just to diagnose, plus shipping and parts and labor. And that assumes I can find a shop to do it, or that TI still stocks the part(s) gone bad. Same old problem with all technology.

the area of your roof is equal to the base (B) times the hight (H) divided by 2.
A = ( B x H )/ 2 = 120
To get the Perimeter of your roof you need to sum the base plus the sides (S)
So P = B + 2 x S


if you have a slope degree of 30 then
B/2 = cos (30) x S
so P = B + 2 x B / 2 / cos(30)
P = B ( 1 + cos (30) )
we also know that
H = tg (30) x B/2
from this last one we can go back to the Area and get a value for B
120 = ( tg (30) x B / 2 x B) / 2
480 x SQRT(3) = B^2
B = SQRT(480/tg(30))

So:
P = SQRT(480/tg(30)) x ( 1 + cos (30))
tg (30) = 1 / SQRT(3) cos (30) = SQRT(3)/2
P = 2 SQRT(30 x (12 + 7 x SQRT(3) ) ) or aproximately 53.8m

Every time you change batteries this will happen to you. First press 2nd then press and hold the down arrow. Hold until their is no black in the background but you can still see the numbers on the screen.

Hi,
It has two batteries CR2032. They should not be removed at the same time. There must always be one battery in the calculator. The calculator should be turned OFF when changing batteries.

Often after you change batteries the screen contrast may be too light and you cannot see anything. The contrast can be adjusted (lightened or darkened). As you adjust the contrast setting,a highlighted number in the upper right corner changes to indicate the current contrast setting; 0 is the lightest, and 9 is the darkest.
To adjust the display contrast:
1. Press and release the [2nd] key.
2. Use one of two keys: (UpArrow or DownArrow)
--- To increase the contrast (darken), press and hold [UpArrow]
---To decrease the contrast (lighten), press and hold DownArrow

Hope it helps.
Thank you for using FixYa.

Wow, I'm in the exact same situation. I've had my trusty TI for 6 years and now all of a sudden this gibberish is on the screen. You're right, there is absolutely nothing you can do to fix it. Guess we'll have to bite the bullet and buy a new one. 

In the short time now i want to know the function about the basic input out function and by the help f this site https://windowsclassroom.com/how-to-enter-bios-windows-10 i will know because i start now this site and its so easy for the all.

Milliliter is a unit of volume, milligram is a unit of mass (or weight). There is no direct conversion between them. 5 mg of water occupies 5 ml. 5 mg of gold occupies about about a quarter of a ml.

This error is due to 3rd-party software not compatible with the Operating sytem. The software is trying to access a memory address (location) reserved for the OS or for an application.

To correct it:

The following procedure will completely reset the calculator. Note that this will erase the memory of the calculator and restore all manufacturer's defaults.

• Hold down the following keys [2nd] [<] and [>] (right and left arrow keys)
• Press [ON]
• Release all the keys at the same time
• Adjust the contrast, if necessary.

One millileter is about 0.033814 fluid ounces, so to convert ml to fl oz multiply by 0.033814. To convert the other way, divide by 0.033814

Refer to page no 13 of user manual of calculator. (TI-30XS / TI-30XB MultiView™ Guidebook - Texas Instruments - US and Canada) It will solve your problem.

Question edited for clarity. Question moved to model category. Solution 10345: Using the Tax Rate Functions on the TI-1795 SV.

How do I use the tax rate functions on the TI-1795 SV?

Refer to the below instructions on how to use the tax rate functions of the TI-1795 SV. To set the tax rate: 1) Input the tax rate, for example, 6 2) Press [RATE] 3) Press [Tax+] To recall the tax rate: 1) Press [RATE] 2) Press [Tax-] To use the new tax rate in a calculation: The following examples demonstrate how this is done on the TI-1795 SV (assumes the 6% rate in the above example has been set). Example: $12.00 + 6% = $12.72 1) Input 12.00 2) Press [Tax+] Example: $12.72 - 6% = $12.00 1) Input 12.72 2) Press [Tax-]

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 finally fixed my calculator~

1. if you have a ti 84 plus silver, plus, or just ti 84, find a friend who has either a ti 84 plus silver, plus, or just ti 84. (as long as the number is the same)

2. link the two calculators together

3. using your friends calculator, press the [2nd] and the one next to alpha [x,t,o,n]

4. go all the way down to [send os]

5. send it to the other calculator and your problem should be fixed

my son dropped his and cracked the screen 2 days ago.Called TI no replacement parts.Spoke to the head of the math dept.at school he also said they have called for repair and no luck. Solution is we have to write a check to the school for $120 since they supply the calculator

Do not even go there. The calculator is pretty basic and does not have memory to store instructions. If you want to take up programming ( a worthwhile endeavor) buy a graphing calculator such as a TI 89 itanium, a TI Voyage 200PLT, a TINspire, or a Casio Graphing calculator FX 9860 SD, ClassPad 330, or some top of the line HP calculators (HP 49G+, HP 50 G).

The foam on the feed roller is probably decayed/ soft. Which has caused the plastic gear that engages that drive gear to wear. If the gear is moved/ spaced over to pick up the 40% that isn't trashed - it'll feed.

I'm going to try to fix my Goodwill purchase anyway. Anything is better that the Canon piece of rubbish I have now. Mybe someone can tell Canon that a few months of use is not enough?
