Question about Texas Instruments TI-1795 SV Calculator

2 Answers


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!

    Thanks for your input. I shall see about getting it cleaned. I don't have the right tools to take it apart. I appreciate your prompt reply.

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

How to solve franctions

Multiplying Fractions:
  1. Make sure you're working with two fractions.
  2. Multiply numerator x numerator, then multiply denominator x denominator.
Dividing Fractions:
  1. Make sure you're working with two fractions
  2. Flip the second fraction upside down.
  3. Change the division sign into a multiplication sign.
  4. Multiply top x top and bottom x bottom.
Converting Mixed Numbers into Improper Fractions:
  1. Convert mixed numbers into improper fractions.
  2. Take the whole (non-fraction) number and multiply it by the denominator.
  3. Add that answer to the numerator.
  4. Put that amount over the original denominator and you will have an improper fraction.
Method for Adding and Subtracting Fractions:
  1. Find the lowest common denominator (bottom number). For both adding and subtracting fractions, you'll start with the same process.
  2. Multiply fractions to match the lowest common denominator.
  3. Add or subtract the two numerators (top number) but NOT the denominators.

My TI-5130 will not add and subtract

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


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.

My calculator is not adding

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

Definition of special product in algebra types and example of special product in algebra

Product means the result you get after multiplying.
In Algebra xy means x multiplied by y
Likewise when you see (a+b)(a-b) it means (a+b) multiplied by (a-b), which we will be using a lot here!
Special Binomial Products So when you multiply binomials you get ... Binomial Products
And we are going to look at three special cases of multiplying binomials ... so they are Special Binomial Products.
1. Multiplying a Binomial by Itself What happens when you square a binomial (in other words, multiply it by itself) .. ?

(a+b)2 = (a+b)(a+b) = ... ?

The result:

(a+b)2 = a2 + 2ab + b2
You can easily see why it works, in this diagram:

2. Subtract Times Subtract And what happens if you square a binomial with a minus inside?

(a-b)2 = (a-b)(a-b) = ... ?

The result:

(a-b)2 = a2 - 2ab + b2
3. Add Times Subtract And then there is one more special case... what if you multiply (a+b) by (a-b) ?

(a+b)(a-b) = ... ?

The result:

(a+b)(a-b) = a2 - b2
That was interesting! It ended up very simple.
And it is called the "difference of two squares" (the two squares are a2 and b2).
This illustration may help you see why it works:
apb-amb-why.gif a2 - b2 is equal to (a+b)(a-b) Note: it does not matter if (a-b) comes first:

(a-b)(a+b) = a2 - b2
The Three Cases Here are the three results we just got:
(a+b)2 = a2 + 2ab + b2 } (the "perfect square trinomials") (a-b)2 = a2 - 2ab + b2 (a+b)(a-b) = a2 - b2 (the "difference of squares") Remember those patterns, they will save you time and help you solve many algebra puzzles.
Using Them So far we have just used "a" and "b", but they could be anything.
Example: (y+1)2
We can use the (a+b)2 case where "a" is y, and "b" is 1:

(y+1)2 = (y)2 + 2(y)(1) + (1)2 = y2 + 2y + 1

Example: (3x-4)2
We can use the (a-b)2 case where "a" is 3x, and "b" is 4:

(3x-4)2 = (3x)2 - 2(3x)(4) + (4)2 = 9x2 - 24x + 16

Example: (4y+2)(4y-2)
We know that the result will be the difference of two squares, because:

(a+b)(a-b) = a2 - b2

(4y+2)(4y-2) = (4y)2 - (2)2 = 16y2 - 4
Sometimes you can recognize the pattern of the answer:
Example: can you work out which binomials to multiply to get 4x2 - 9
Hmmm... is that the difference of two squares?
Yes! 4x2 is (2x)2, and 9 is (3)2, so we have:

4x2 - 9 = (2x)2 - (3)2
And that can be produced by the difference of squares formula:

(a+b)(a-b) = a2 - b2
Like this ("a" is 2x, and "b" is 3):

(2x+3)(2x-3) = (2x)2 - (3)2 = 4x2 - 9
So the answer is that you can multiply (2x+3) and (2x-3) to get 4x2 - 9

I have a Casio fx-115ES; I have followed the manual for creating and multiplying matrices. The matrices have been simple, 2x2 for each, but it returns with "Dimension Error". Any suggestions? Thank you for...

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.

How do I add Exponents on my T1-30xa calculater

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.

I can't seem to do simple subtraction with my Victor 1208-2. When I subtract say 5-4, I get a negative 9. Is there a setting or do I need to press something different to get simple subtraction to work?

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.

TI-84 problems

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.
