When you put a number in and then push minus, then the next number and equal, it does nothing.

Equals is used during a calculation of division, percentage, multiplication, etc. Use the total key or * key for a total of substraction or addition.
If this helps, please rate me. Thanks, Patty

You have to press + sign to get the answer on the screen. It won't print substraction answers. This is a totally weired calaculator.

### BorrowR50from mom and R50fromdad=R100 PayR97forT-shirt = R3. Give Mom R1, gave dad R1 back and I kept R1. Still owns Mom R49 and Dad R49. But R49 + R49 = R98 plus my R1 = R99. Where is the other R1???

You state R50 minus R1 comes to R49 for both and then you add your R1 ?
So if you gave your R1 to Mum and Dad you would subtract 0.50 from what you owe them .
Being 48.5 plus 48.5 and this equals R47
So the R1 is in your pocket as with a credit account it works opposite to a debit account.

In a credit account payments in are subtracted (basic accounting )
Withdrawals are added to account balance.
It is opposite to a savings account

### How do you do long division

Let's do an example, outlining all the steps.

528 divided by 6
__88
6)528 does 6 go into 5. How many times does 6 go into 52. So put
48 the 8 above the 2. Next multiply 8 times 6 and put the answer
---- under the 52. Subtract 48 from 52. Write the 4 under the 8 in
48 48. Now bring down the 8 from the 528. How many
48 times does 6 go into 48. 8 times. Write the 8 above the 8
--- in 528. Multiply 6 by 8 and write the answer under 48, and
0 subtract from 48 leaving 0.

Let's check to see if we did it correctly. Does 88 times 6 equal 528? Yes. So we have confirmed that we did it correctly.

Good luck.

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.

### Casio FX-115ES Scientific Calculator

I have done the calculation using the the shortcut key [x10^X] to enter the exponent,and I got the correct result.
I also did the calculation by explicitly typing the 10^10 factor and I obtained the correct result.
The syntax error may come from your using the minus - sign for subtraction rather that the change sign key (-)

### One number is 11 more than another number. Find the two numbers if three times the larger number exceeds four times the smaller number by 4.

Do you need help doing your homework?

If so, here's a first attempt. It may be correct, and it may not be.
It's up to you to understand the process, and to make any needed corrections.

X minus 11 equals Y.
So, X is larger than Y.
So, 3 times X minus 33 equals 3 times Y.
Thus 3 times X equals 3 times Y plus 33.
Also, 3 times X minus 4 equals 4 times Y.

So, (3 times Y plus 33) minus 4 equals 4 times Y.

Thus 0 times Y plus 29 equals 1 times Y.

So, Y equals -27.

### I do not have the manual. If I want to add or subtract do I put the total amount in and than hit the plus or minus key ? i.e., \$128,000 -10000. do I hit the minus before the amount or after? -1500....

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

### 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.

### I can't seem to do simple subtraction with my Victor 1208-2. When I subtract say 5-4, I get a negative 9. Is there a setting or do I need to press something different to get simple subtraction to work?

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.
