SOURCE: Nothing happens when I press a number??

Hello,
There is no lock button. Calculator may be configured to be in computational mode you are not familiar with: It may be set to do base calculation on base 5, hence the p (pental). Press the reset button on the back, and the default configuraion will be restored.
You should give some time to learn the different mode of calculations.
Hope it helps.

How to find the determinant by Sharp ELW516 Scientific Calculator


Press the MODE key. and press 4 for MATRIX.
To enter a matrix press the MATH button and choose 2 for EDIT. Determine the size of your matrix by typing in the row x column value (maximum 4). Then press =. Type in the values in your matrix. After each value press = to move to the next part of the table. Once your matrix is complete press ON and then the MATH button. This time choose 4 for STORE. Select the matrix name you would like to store your matrix in - for example choose 0 for matA. Now press MATH and press the down arrow key once. Select 6 for CALC and choose 0 for det (determinant). Then input the matrix you want the determinant of by pressing MATH and 1 for MATRIX. Select the matrix you would like to work with eg, matA and press then press =.

Sharp Advanced D.A.L. seems locked, display shows a P in upper right corner by 0.


Your calculator is set to do arithmetics in base 5 (PENTAL), that is why the numbers are displayed with a small p. The only number keys that work are 0,1,2,3,and 4. Number 5 is represented as 10p and 6 is 5 (10)+1=11p.
To revert to the decimal numeration, press the [2ndF ] key followed by [+].

I have a Casio MS-8TV calculator and want to change the VAT rate to 20% (usage in UK), please. Val


How do I program tax rate into my calculator?
Non-printing models (also applies to HR-8TE printing calculator):

1. Press [AC]
2. Hold [SET/%] key for about 2 seconds
3. Press [TAX+]
4. Input the tax rate
5. Press [SET/%]


Printing models (except HR-8TE):

1. Have calculator in "print" mode
2. Press [CA]
3. Hold [SET/%] key for about 3 seconds
4. Input the tax rate
5. Press [TAX+]
6. Press [SET/%]
^Top I am having a problem registering the ClassPad 300, it keeps telling me my product key is wrong.
Enter only the numerals, not the letters.
^Top What features do our calculators have?
The attached chart shows comparisons of the different calculator models. This includes graphing, scientific and printing calculators. download the chart here
^Top What is the [F CUT 5/4] switch or [DEC] F, 0, 2 button for?
The HR-8TE/HR-8TM have a [DEC] key with F, 0, 2, and 5/4 over it, while many other calculators models have a switch labeled [F CUT 5/4].
The button or switch can control rounding off to a certain number of decimal places. F is floating point (no F indicator on screen), 0 rounds off to 0 places after decimal point, and 2 rounds off to 2 places after decimal point.
The 5/4 applies to either the 0 or 2 modes, and describes the type of rounding off that is performed. The calculator will round down if the digit after the one you are rounding to is 4 or lower, and round up if the digit is 5 or higher.
^Top What is the [5,4,3,2,1,0 ADD (2)] switch used for?
This switch is used to determine how many decimal places your answer is displayed in.
ADD (2) is often used for monetary calculations, so that it is not necessary to enter the decimal point. It is automatically placed two decimal places from the end for cents. For example, entering 123 will display as 1.23.
^Top Why do I get 111.1111... when I calculate 100+10%?
This is a markup on price procedure. The formula is as follows:
Markup%=(Markup Price-Cost)/(Markup Price)
^Top Why do I get the wrong answer when doing a percent calculation?
Make sure that you are following the correct procedure.
Adding 10%: 200 [×] 10 [%] [+]
Subtract 10%: 200 [×] 10 [%] [-]
^Top What tests are calculators permitted for?
AP Calculus requires a graphing calculator.
Any graphing or scientific calculator is permitted on the following as long as it does not have a QWERTY keyboard, electronic writing pad or a pen-input/stylus-driven interface:
PSAT/NMSQT, SAT I
SAT II Math, IC & IIC
AP Statistics (graphing expected)
AP Chemistry
AP Physics

When i type the letters on my keyboard, the numbers show up instead. i don't know how to revert the system or functions back to normal. i must've accidentally pressed a button to change the characters when...


Sounds like the keyboard is in NUM LOCK mode

They keys map like this:

7 8 9 = 7 8 9
u i o = 4 5 6
j k l = 1 2 3
0 . = m .

Look for the NUM LOCK key on your keyboard.

Typically, you press the FN key (lower left corner) and the NUM LOCK key (typically towards the upper right) together to put the keyboard back into regular mode.

Solve for x: x/3-1/5=4/3


Press [math] [0] to put the calculator into equation solver. Then you input your equation in 0 = format. So, the equation x/3 - 1/5 = 4/3 would be input as 0 = x/3 - 1/5 - 4/3 . Then press [enter] .

Hi i have the canon p170-DH and i cant subtract. example: 4-4= -8 not 0


Hi....by looking at the date you posted this question, you may have already found the answer, but just in case you haven't......the procedure for adding and subtracting on these calculators is completely opposite of a regular calculator. On a regular calculator, you would input 4 - 4 = 0. On these type of calculators, a number's positive or negative status is keyed in AFTER the number, instead of before it. Therefore, you input 4 + 4 - (notice you DO NOT input = at the end, but if you are in print mode, you will need to hit your total key, which looks like an asterisk, where the = would normally be, in order for the final value of your calculations to print on the paper tape.

Multiplication and division equations are done exactly as they are on a regular calculator....4 x 4 = 16.

Hope this helps. If you have your owners manual, it should also give you some examples of how to perform calculations with your calculator.

Canon F-502 statistycal scientific calculator


As I added on to the previous solution on the other problem.


"Okay, I did what the best solution did and worked with it.

"1. press 2nd F (left top corner)
2. ENG/FIX (the button next to 2nd F)
3. press 0 (if you don't want calculator to round off any decimals)"

In order to get your exact value of pi, in step #3, instead of 0, press the decimal [ . ]
This should give you no decimals when entering a number and give you 3.141592654... when you input pi.
Hope that works/helps."
