This calculator works fine according to my "bank teller" daughter. But I just don't understand how to hit the keys in the right order to get what I want. I am trying to just run pluses and minuses in my checkbook. She told me to hit something after each number that is different than what you would do on a regular calculator (which I about to go back to) but I don't know what it was. I need help. Let's say I wanted to take my current balance and subtract a couple of checks and then add in a deposit and get my balance???? I am missing something.

Hit the plus sign after numbers you want to add and hit the minus sign after the numbers you want to subtract.

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

The manual mentions an add mode, turning the calculator into an adding machine.

If this is the case, you can do this test and see if it works to confirm that it is acting like an adding machine.

4+

3-

5+

*

Think of these as integers. The 4 is positive, the 3 is negative, the 5 is positive. When we add all these integers together, we get positive 6.

Good luck.

Let me know if you have any questions.

Check your owner's manual. Ok, ok I know you lost it, but you can download one from Canon. Is it possible you are exceeding the capacity of the machine? Is it possible you are low on ink?

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.

To calculate 7-2=5 (for example) on a business calculator:

7 + (all positive entries are followed by the + key)

2 - (all negative entries are followed by the - key)

* (The Total key, marked with a star or a T finishes the calculation.)

It seems strange to people who use handheld calculators, but this is how adding machines have worked since the days of hand-cranked adding machines. The subtotal key (marked with S or a diamond) prints the running total without clearing it back to zero.
