SOURCE: Hi, I have a Casio calculator fx-991MS giving me wrong answers!

Hello,

I am only looking for a plausible cause of the error, because I do not believe your calculator can make such a mistake. I think you **accidentally activated the Exponential display format** and did not pay attention to the small, raised -03 that came at the end of the number displayed. It is a common mistake for those not very familiar with Scientific or exponential notation.

Let us try to reset your calculator to the normal (floating point) format.

Press the [MODE] key a number of times until you reach a screen that has FIX, SCI, NORM and under each one a number (FIX 1, SCI 2), Norm 3). To have the number of decimal place you gave in your result (4 decimal digits), you press 1 to select Fix then 4.

Be aware that scientific calculators usually stop displaying results in floating point format ( 0.0000045 ) if the number is smaller then 0.001. So basically, 0.00099 will be displayed as 9.90-04, -04 being raised above the level, and in smaller size.

Hope it helps.

I found it by myself, I can help you.

1. Press (AC)

2. Hold (Rate) for about 2-3 second

3. Press (Set / TAX+)

4. Input the tax rate

5. Press (Set / TAX+)

6. Hold (Rate) for about 2-3 second again

7. Press (Set / TAX+) again

And Then you can test the rate .

Here's how to use the MU/MD key. Say you want your item that COSTS you $120 to be priced such that you end up with a 40% margin. MU'MD calculates the final price to achieve the margin.

Enter: 120 X

Enter: 40 MU'MD

Result: 200.00

Proof: 200 - 120 = 80 / 200 = 40%

Essentially the same as using the COST/ SELL/ MAR keys.

The Casio HR-100Tm manual is pretty pathetic. Expected a better one on their website, but alas.

It is used for calculating markup. For example, if you have an item at $100 and have a 20% markup, you get $120.

There is a program on page 253 of the manual (http://support.casio.com/manualfile.php?rgn=5&cid=004002013) to get the prime factors of any number. You could modify the program to get all the factors.

Another way would be to do it manually. I start with the number 1 and go up to the square root of the number. The square root of 120 is 10.95, so let's go up to 11. Using 120 as an example:

120 /1 = 120 thus factor is (1, 120)

120/2 = 60 thus factor is (2, 60)

120/3 = 40 thus factor is (3, 40)

120/4 = 30 thus factor is (4, 30)

120/5 = 24 thus factor is (5, 24)

120/6 = 20 thus factor is (6, 20)

120/7 = 1.7 thus 7 not a factor

120/8 = 15 thus factor is (8,15)

120/9 = 13.3 thus 9 is not a factor

120/10 = 12 thus factor is (10,12)

120/11 = 10.9 thus 11 is not a factor.

Good luck.

Make sure your calculator is set to the desired angular mode.

The quotient of 120 divided by the tangent of 68 radians is about -58.82, as your calculator is giving you.

The quotient of 120 divided by the tangent of 68 degrees is about 48.48 . The quotient of 120 divided by the tangent of 68 grads is about 65.97 .

There seems to be two completely different issues here.

By default the calculator will try to show a symbolic result. 1 divided by 120 is 1 over 120, after all. If you don't want to see fractions at all, press SHIFT MODE 2 to switch to the LineIO mode.

The other is the display mode. 1/120 is about 0.0083. Again, by default, the calculator automatically switches to scientific notation for numbers whose magnitude is less than .01, so it shows the number as 8.3x10-3. To change this, you have two choices. Press SHIFT MODE 6 to select the fixed decimal mode, and the calculator will prompt for the number of digits to the right of the decimal. Alternatively, press SHIFT MODE 8 2 to select the Norm2 mode. This won't switch to scientific notation until the magnitude of the number drops below 10-9.

Calculators only have two choices when a number gets close to zero. It can either round it off to zero, or switch to scientific notation. It doesn't matter how many digits the calculator can display, at some point it has to make the choice.
