Re: Percentage Key

I've been searching for the solution to this problem, as well. Apperently, there's no user's manual for this calculator. I'm going to call Casio on Monday to see if they can send me some sort of instructions. (800)962-2746 or (609)395-0154

good luck!!

Hmmm. Could you give more details? Are you wanting to find a percentage? If so, here's an example - 10% of 100 is 10.

Multiply 100 by .10 = 10.

So to find the percentage of a number, multiply the number in question by the decimal version of the percentage. 8% is .08, 15% is .15, etc.

I hope that helps!

You can try pressing "alpha" or "2nd" and then pressing the key you saw the percent sign on.

here is a temporary solution in case that doesn't work:to enter a percentage up to write the digits before the tens and ones (if any, and if not, just type a zero), a point, and the last two digits.ex:

To write down the answer, take all the digits, take off the point, if the percentage is 99% or less, don't write the zero on the right of the period, and add a percent sign.

Hi,

You can use either of this 2 equations.

ex: 75% off of 20

Equation 1: 20 minus (-) 75% = 5

Equation 2: (20*0.75) = 15 then press Ans key

20 - Ans = 5

Hope this helps.

Enter the number, press =, then press the S--D key (located above the red DEL key).

For example, to see what 25% is, type . 2 5 = S--D

Note: if you're in the LineIO mode you will see something like 1 _ 4. If you want to see it as a "real" fraction, press SHIFT MODE 1 to switch to the MathIO mode.

Sorry, but you cannot calculate percentages at the pressing of a key. The calculator does not have a key for that. You will have to do it yourself.

To convert a decimal result to a percentage, multiply it by 100: MOVE the decimal mark two places to the right.

To convert a percentage into a decimal number, divide the number by 100: MOVE the decimal mark two places to the left.

There is no key nor command to calculate percentages. But that is easy to correct.

Percentages

To go from a decimal result to a percentage, move the decimal mark 2 places to the right. If you have no decimal mark as with integers, put a decimal mark at the end of the number pad it with zeros, then move the decimal mark 2 places to the right.

Ex: 0.73 in % gives 73.0%

Ex: 2.33 in % gives 233.00 %

Ex: 5 in % 5=5.00 becomes 500%

Fractions

The calculators has a command to convert a decimal number to a fraction. The command is called >Frac or To frac. You find it under the MATH key.

Enter a number (decimal or fraction)

Press [MATH][1:>Frac]

Command echoes on main screen after the number you entered.

Press [ENTER] the result is displayed as a fraction.

The TI 84PLUS and TI84PLUS Silver edition OS has seen a major upgrade to version 2.53 M(ath)P(rint). If you play a lot with fractions this new OS will allow you to do a lot more than what is described above.

- If the number entered or stored in answer memory is a decimal number it will be converted to a fraction.
- If the number you entered is a fraction, the result will be displayed as a fraction but REDUCED to its simplest terms.
- For example 6/9 becomes 2/3

Hi,

**Logarithms in base 10 :Common logarithms**

**Logarithms in base e : Natural logarithms**

Don't forget to rate the solution and don't be stingy: 4 thumbs up won't leave you any the poorer.

- The calculator has a key labeled [LOG]. It allows you to calculate the common logarithms (logarithms in base 10).
- To calculate the common logarithm of a (positive) number you type in the number, press the [LOG] key .
- Ex: 15.32 [LOG][=] gives 1.1852558765

- The calculator has a key labeled [LN]. It allows you to calculate the natural logarithms of positive numbers.
- Ex: natural log of 15.32 is entered as
- 15.32 [LN] gives 2.729159164

Don't forget to rate the solution and don't be stingy: 4 thumbs up won't leave you any the poorer.

I have a Casino MS-80S and yea, the percentage works different. As example to take 100 and subtract 10%, this is what I do: 100 X 10% - and then I get the answer 90 after I press the minus key. To add the percentage instead, 100 X 10% + will give me an answer of 110, after I press the plus key.

Lets say Your

MRP = 199

BESTSALE = 130

Now you want to calculate that howmuch percentage of BESTSALE i.e 130, will be added to get MRP i.e. 199.

If m right what do you want, then use the following formula:

Percentage = ((MRP/BESTSALE) - 1) x 100

In your case 199/130 = 1.5307....

So 1.5307 - 1 = 0.5307

Then 0.5307 x 100 = 53.07 %

Thanks
