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.

Hi. Try this steps on using your math calculator for the percentage function.

Hope This Helps

Step 1. Note that not all calculators behave the same way as far as the percentage key is concerned. Thus, test the examples in this article on your calculator. If your calculator does not have the percent key or does not behave in the way described here, don't despair - you can still use it to calculate percentages, it's just that you will have to press a few more buttons.

Step 2. Let's calculate a tip on your restaurant bill. Suppose your bill happens to be $64.35 and you would like to leave 15% tip.

Type the following into your calculator: 64.35 * 15 %

Answer: 9.6525 or $9.65 after rounding.

Most simple calculators will give an answer right here without having to press the = sign. If yours does not, press = and see if you get the right answer.

Alternatively, you can calculate this percentage by typing in

64.35 * 15 / 100 or 64.35 * 0.15

Thus, you may have observed that all that the percent key did here was division by a hundred.

Step 3. Let's calculate a grade percentage - say you got 34 out of a maximum of 40 points.

To figure out your grade percentage type in: 34 / 40 %

Answer: 85

Alternatively, without the percent key: 34 / 40 * 100

Step 4. Let's calculate a sale price on those shoes that originally cost $139, but are now discounted by 35%.

On your calculator type in: 139 - 35 % =

Answer: 90.35 or $90.35

This calculation is amazingly easy with the percent key! Alternatively, you would first have to calculate what the 35% of the $139 is and then subtract it from 139:

139 * 35 / 100 = 48.65

139 - 48.65 = 90.35

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.

The formula is 200/700 equals the percentage;if you're in columns a, b, and c, the formula in c1 will look like:

=b1/a1.

Then you can format the cell to show the number (.2857) as a percentage (28.57%).
