Question about Texas Instruments TI-1795 SV Calculator

My TI-1795+ will neither do simple add, subtract or multiplying. When I enter a figure it shows only part of the numbers I enter and comes up with a wrong answer. HELP!

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.

Has something contaminated the keyboard? Most likely something liquid. If it is not displaying the numbers as you enter them, there is something wrong with the keyboard. It will need to be taken apart and cleaned. MM85

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!

Your calculator is fine. It is an adding machine first, so it uses adding machine logic and you hit the star button to print the total on the tape. The equals sign is only used when multiplying and dividing.

Adding machine logic is as follows:

5+ total 5

3- total 2

7+ total 9

* print out total

Good luck,

Paul

It probably uses adding machine logic. Try the following example.

3+

4-

5+

*

You should get 3, -1, and 4 on the screen, the running total. The tape should show the +3, -4, +5, and finally 4, the numbers that you entered and the total. Think of each entry as adding/subtracting integers on a number line rather than 3+4-5;)

Let me know if you have any questions.

Quick-Start Guide
When you enter an expression into the calculator, the calculator will simplify the expression by expanding multiplication and combining like terms. At this point the calculator will attempt to factor the expression by dividing a G C F, and identifying a difference between two squares, or factorable trinomials. Use the following rules to enter expressions into the calculator.
Variables
Any lowercase letter may be used as a variable.
Exponents
Exponents are supported on variables using the ^ (caret) symbol. For example, to express x 2, enter x ^ 2. Note: exponents must be positive integers, no negatives, decimals, or variables. Exponents may not currently be placed on numbers, brackets, or parentheses.
Parentheses and Brackets
Parentheses ( ) and brackets [ ] may be used to group terms as in a standard expression.
Multiplication, Addition, and Subtraction
For addition and subtraction, use the standard + and - symbols respectively. For multiplication, use the * symbol. A * symbol is optional when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * ( x + 5 ) can also be entered as 2 ( x + 5 ) ; 2 x * ( 5 ) can be entered as 2 x ( 5 ). The * is also optional when multiplying parentheses, example: ( x + 1 ) ( x - 1 ).
Order of Operations
The calculator follows the standard order of operations taught by most algebra books - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. The only exception is that division is not currently supported; attempts to use the / symbol will result in an error.
Division, Square Root, Radi cals, Fractions
Division, square root, radi cals, and fractions are not supported at this time. A future release will add this functionality.

that's all I can say basically I learned it this way.

Is it subtracting, multiplying, dividing? Check the way you are entering your numbers.

About 56%. Divide 95000 by 215000, multiply by 100, then subtract from 100.

Calculator should be in [MATRIX] MODE

Try the matrices 2X2 matrices matA [1,2,3,4] matB [5,6,7,8], Add them, subtract them, multiply them, take the square of each. If that works for these matrices, then it must be your data. Be careful with negative numbers. To enter those, you must use the change sign (-).

There is also the possibility that the instructions were misread.

Hello,

There is a rule of Algebra, that says

**(a^m)[x] (a^n) = a^(m+n) **

a is the base of the power, n, and m are the exponents. As you can see, multiplying two powers of the same base is equal to the power of the (common) base with the sum of the exponents.

If that is what you had in mind, the calculator uses the rule correctly and no intervention from you is necessary.

**If you enter (2^4)[x](2^6), the calculator will give 1024, which is 2^10. **

I may be wrong, but what you call add exponents refers really to performing addition where addends (the terms you add) are arbitrary powers, such as

2^7 + (5.5^3) - (1/3)^4

Once you enter a power term, the calculator calculates it and the result is now just a number. It can be added, subtracted, multiplied

For the exemple above

2 [Y to the x] 7 + (5.5)[Y to the x] 3 -(1/3) [Y to the x] 4 [=] yields 294.3626543

For the cube of 5.5 you can use the key combination [2nd][X^3]

Hope it helps.

When you want to complete a problem on an adding machine, such as "7 - 3," you would not key in "7," then the subtraction sign, then "3" and then an equal sign. If you do, then you will get an answer of "-4," and you know that is not the correct answer. Again, you have to think like an accountant when you are working with your adding machine. To figure this subtraction problem on an adding machine, you would need to key in "7," the addition sign, "3" and then the subtraction sign; you would get the answer of 4. You are actually working the problem as "7 + (-3)." This would be true on most modern day machines. In order to subtract, you have to add the negative number.

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.
