SOURCE: 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.

the function buttons are labeled + and -

to add put in the number then press the + button then put in the next number and + and son for all the numbers you are adding up

to subtract put in a number then press the- button ,then put in the next number and press the - button and so on

to do a combination calculation put in a number then press the + button and so on until you come to a number that you want to subtract in which case you put in that number then press the - button and if the next number is to be added ,put the number in and press the + button

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.

SUM means adding not subtracting. so if you were wanting to add the total (the sum) of the amounts of the hundreds and the tens would be 170 plus 130 which would be 300 but the remainder from subtracting 130 from 170 would be 40. That would leave the single units 5 minus 4 of which the remainder is 1. So, the remainder from subtracting 134 from 175 is the reminder of subtracting the one hundred from the one hundred which is zero added to the remainder of subtracting the tens (70 minus 30) which is the remainder of 40 plus the remainder of subtracting the units of 5 minus 4 which is 1. So you need to add the 0 and the 40 and 1 which is the remaining sum of 41.

That depends on what you're trying to undo. If the last thing you did was add, then you subtract to undo. If the last thing you did was subtract, then you add to undo.

If one or both numbers are in polar form, convert it/them to rectangular. Once both numbers are in rectangular form, simply add the two components separately: Add the two x components together, and add the two y components together.

If you're asking how to do this on a particular calculator, please specify the make and model.

Hello,

I do know what calculator you have but on most calculators you have digit keys to key in numbers, operation keys (multiplication, division, addition, subtraction), function keys (log, exponential, %, square root, square or a power) and you have the = key to obtain the result of the calculation.

Press the [ON] button

To add 2 numbers, exemple 12 and 13

12 [+ key] 13 [= key]. Calculator displays 25, or 25.00 or 25.0000...

To subtract

13 [- key] 7 [=key] . Calculator displays 6 or 6.00, 6.0000....

To multiply

32 [x key] 5 [= key]. Calculator displays 160.

You may have memory keys, to store values. They may be labeled M to enter a number in memory, M+ to add a number to the one already in memory, M- to subtract from the number already in memory.

Hope it gets you started.

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.

Put the figure which you have to multiply in cell A1, Put the figure in cell A2 by which you have to multiply by, type =A1*A2 in cell A3. You will get the right answer.

You may substract, multiply or add by this method by appropriate mark in cell A3 in between A1 and A2.

First keep the manual aside .

From "columns of figures ",do u mean a set of calculations.If this is the case, if your calculator has brackets{ } or [ ] ,use this function to add or subtract columns of figures.

Eg: [789+546+123+852+6547+65]=8922

OR

[789+587+6598+458] - [ 548+2587+456+584]=

8432 - 4175 = 4257

I hope this solution solves your problem.
