Question about Texas Instruments TI-1795 SV Calculator

How do I add several numbers then get the running total when I have a negative number to figure in?

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.

SOURCE: Add number of checks

on the 5660... on the printer tape there is "off" "on" IC (for item count) and GT (which might be grand total)

for every entry of $check you add the item count will total to the left of the register tape.

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.

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.

Could it be that it has adding machine logic and not calculator logic?

Let's do an experiment. 3+ 3+ 5-. Is the answer 1?

If so, it is working like an adding machine. Every number you enter is considered positive or negative and it keeps a running total.

Let me know if you have any questions.

Good luck.

It looks like it may have adding machine logic.

Do this key sequence:

5 + 5+ 6-. Is the answer 4?

Each number you enter is positive or negative and it is just keeping a running total, rather than adding and subtracting numbers.

Let me know if this helps.

Good luck.

There's a negative button and a minus button. I think you're accidently pressing the negative button. The actual subtraction button is the red "-" button above the "+" button. I hope this helps, but if all else fails, you can always add a negative!

You can download the manual from

http://downloads.canon.com/cpr/software/calculator/P170-DH-(USA-HWB).pdf

128000 - 10000 then press = or chain the calculation by pressing + or - and the number you want to add or subtract.

use the + key after each number to add the total will appear on screen. When all numbers have been added, enter number to subtract and then press - key. The subtracted number will appear in read on the paper (if two color). and then press the star key to get total.

Big calculators work a little different than handheld calculators. Like the above commentor explained, if you have a basic "whats 100 minus 20?" You have to entered as 100 + 20 -- And when you hit the minus button at the end, it will give you the total. 100 is the positive number, and the 20 is the negative number that your subtracting. Also you can hit 20 -- 100 + and get the same total because you entering 20 as the negative and 100 as the positive, just in reverse.

Enter a number, then press + for positive, or - for negative.

Example,

47 +

12-

___

35

It is bass-ackward from most calculators, and you will screw up with any other calculator when you get used to it.

Just remember what value the number is that you just put in (i.e. positive or negative.)

With an adding machine, which is what this is, you enter the number followed by the + or -. If you wanted to add 10+20, you would enter 10 then + then 20 then +. This would show your answer. If you are using the printer and you wish to see the final answer on the paper, hit the * key and your answer will print.

If you are subtracting, let's say 100-40, you would enter 100 then + then 40 then - then *. Adding machines expect you to enter long strings of numbers to total. You may have both positive and negative numbers. So, you always enter the number first followed by either positive + or negative -.

You might have 100 + 25 - 37 - 1 + 50. For that enter:

100+25+37-1-50+ then *

Different than a calculator but the same for all "adding machines". This machine should really be called an adding machine since that is the kind of input it is looking for.

First think how you would solve this problem yourself on a piece of
paper. Then try programming it using the things you learned (if they've
given you this assignment without teaching you to multiply, subtract
and use if's, drop the course).

Well here is an idea.

Take the total kilowattage and send it to a function. What the function will do is subtract 14KW from the total Kilowattage and add the amount for the first 14KW then subtract 85KW from the total KW and add the amount for the 85KW. But once you subtract the number of KW from the total make sure to check if the total KW isn't negative, if so just break out of the function and return the total due.

Or if you have formula for how much the rate grows over how many miles.

For example lets say the rate grows by $1 every time the KW doubles you could have something like

int rate = 1; //Begining rate

int KW = 14; //First flat rate

int amount; //total amount they have to pay

while(totalKW > 0)

{

totalKW -= KW; //subtract the first rate

if(totalKW <= 0) //check if too much subtracted

break; //if so break

amount += rate; //add the rate to the total

rate += 1; // Add $1 to the rate every time

KW *= 2; // KW is doubled

}

The asterix (*) next to the big fat plus key prints the running total.

Just figured that out. Why doesn't Canon have a downloadable manual for this thing?
