# Percentage Key How do I get the percentage key to work? Ex: I want to add 15% to a certain number... on other calculators I can just enter 45+15% (and hit the percentage key). This doesn't seem to be working for me. Is there a way to set this?

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!!

### How do the memory keys work?

Memory keys normally work by adding and subtracting values to them. It looks like you have two memories available, memory I and memory II. (M- I M- II M+ I M+ II) You recall these values with the MR(C) keys to use them in other calculations. Finally, you can clear the memory using the MC keys. Sometimes there is not a MC key. In this case, the easiest way to clear the memory is to recall the memory, multiply it by -1, and add it to the memory. This should set it back to zero.

As an example, if we enter 5 M+ I, 10 M+ I, and then hit MR-I, we should get the answer of 15. If we then enter 13 M- I, and hit MR-I, we should now get an answer of 2. Now if we hit MC - I and then MR - I, we should get the answer of 0.

Let me know if you have any questions.

Good luck,

Paul

### Where is the percentage button?

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:
• 56%=0.56
• 28%=0.28
• 132%=1.32
• 4243%=42.43

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.

### How do I use the percentage function on this calculator? Such as subtracting 75% off of an amount

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.

### How do I convert from decimal degrees to degrees, minutes, and seconds?

You have a key, the label of which is the degree sign, the apostrophe and the double quotation mark. It is located between the change sign key (-) and the [HYP] key.

To enter an angle with degrees, minutes and seconds you use the key to separate between numbers
Ex: 18 deg 0' 45" you press 18 [Deg ' "] 0 [Deg ' "]45 [Deg ' "] [=] As you type the calculator displays 18 deg 0 deg 45 deg but the result will show correctly. You have to press the key after the seconds figure, otherwise you get a syntax error.

While the foregoing result is still in answer memory, if you press the [Deg ' "] key the result will be displayed in decimal degrees.

The key is used to enter the DMS values and also to toggle between DMS and D.D.
