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.

What is 67,872 divided by 24, step by step?


First, find out how many whole times 24 will go into 67
67/24 = 2 with a remainder that we don't care about. Write down 2
Next, multiply that answer (2) by 24 2 X 24=48
Subtract that 48 from 67 67-48=19
bring down next digit (8) append to the19 198
divide 24 into 198 198/24=8 Write down 8
multiply that answer by 24 8 X 24 =192
Subtract that 192 from 198 198 - 192 = 6
bring down next digit (7) append to the 6 67
divide 24 into 67 67/24 =2 Write down 2
multiply that answer by 24 2 X 24 = 48
subtract 48 from 67 27-24=19
bring down next digit (2)append to the 19 192
divide 24 into 192 192/24 = 8 Write down 8
multiply that answer by 24 24 X 8=192
subtract 192 from 192 192-192=0 You're done!
Your answer is the numbers you wrote down after the divisions = 2848

Answer always appearing


Minus and change-sign are two completely different things. Minus is used to subtract one number from another. When you press minus when the input line is empty, your telling the calculator to subtract. The only way it can subtract the number you're about to put in is to subtract it from something else, and that something else is the previous answer, hence the "Ans."

If you want to input a negative number, use the change-sign key. If you want to subtract one number from another number, use the minus key.

Try pressing the plus key when the input line is empty. You'll get Ans+ in this case as well, The same with multiply and divide, among others, and for the same reason.

I am unable to subtract


The way to do math on this calculator is a bit different than on others. To start off, when doing subtraction, you must press the + key. This tells the calculator that you are working with a positive number.

Say you have $588.43 in you check book but you spent $136.92. The buttons you press on the calculator will be as follows:

588.43 + 136.92 -

The positive total of 451.51 will be on your screen. If you are using the print function as a way of keeping track, press # to print the on screen total.

Just remember, enter your first number and hit +. After this, each number that you are subtracting will have a - behind it.

How do you subtract fraction on a caluclator. problem: 6/7-2/5


A fraction is just a number like (almost) any other. On most calculators, as you enter 6/5 the calculator displays its decimal value. When you press - the calculator waits for a number 2 then / then 5. Once you press the equal sign it will calculate 2/5 then subtracts it from the preceding result. The priority rules favor multiplication and division over addition and subtraction.

On some calculators you can keep a fraction in fraction format and operate on it with other fractions, and the result may be obtained as a fraction.
The gist of the story is that ON A CALCULATOR operations on fractions as performed like operations on any number.

How do I add and subtract on this thing?


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.
