Help with adding numbers

My grandkids have been playing with the buttons and now I can't add numbers. Every time I enter a number and hit another number it just goes across the screen instead of adding them. Also I can't get the blinking tax% off the screen. I don't use the print paper and I can't seem to get it to work not using it. Where do I need to put my settings. Is there anyway to look at maunals online?

Re: help with adding numbers

Sounds as though you have it set to the rate set position it just needs to be in the on position if not printing.

What is the default setting for the f cut 5/4 and the 4320 add 2 I don't know what to have these options set at thanks EW Seattle

The selector you are asking about is the "decimal selector". The result displayed/printed, will be in a format according to the position that you have selected as follows:
f = floating (the result will be in the number of decimal places that were entered on the keyboard
4= fixed 4 decimal places (x.0000)
3= fixed 3 decimal places (x.000)
2= fixed 2 decimal places (x.00)
0= fixed 0 decimal places (x)
add 2= (add mode*,fixed 2 places) ($.00)
Note* "ad mode" automatically enters the decimal place when entering the number on the keyboard. If you enter "123", the displayed ammount will be "1.23". If you enter "1", the display will read ".01". This is a useful setting when adding a list of numbers in a dollars/cents format, however, be careful, if entering a whole dollar ammount "three dollars" be sure to enter the decimal point, or enter the number as "300". If you don't, the result will be ".03", instead of the 3 dollars you intended.

How do I raise the power of 30 on calculator?

If you are using an HP 12c or have the button on the calculator "yx" you first enter the number you wish to raise (y) then enter then the power (x). For instance to find 230 (2 to the power of 30) you input the number 2 then hit the enter key on the calculator, then input 30 and hit the yx button.

If you have another model of calculator the procedure may be similar or the buttons. Play around with it. By the way the solution to 2 raised to the 30th power is 1,073,741,824.

How do I get this calculator to substract

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.

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.

Tring to subtract

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.
