Inputting -32 in my scientific calculator gives the answer -9, when it should be +9. How do I get the right answer?
	I have an FX calculator and am trying to change the mode to comp. I have pressed all the buttons and cannot get comp on the display, why?
	I have just recently purchased a new FX calculator, I am trying to calculate percentages but I am getting the wrong answer, is my calculator faulty? E.g. 100 + 10% = 111.11
	I have an FX calculator and am trying to do a simple calculation, and I am getting the wrong answer. E.g. 10 + 2 x 2 = 14, when the answer should be 24, what is wrong?
	I had an old FX calculator and used the sin, cos and tan keys, in the new calculator that I have bought I do the same calculation and I get 0 (zero) E.g. 205 ÷ 42 tan = 0. Why is this happening?
	What do I press when my screen displays an error message?

	Inputting -32 in my scientific calculator gives the answer -9, when it should be +9. How do I get the right answer?
	The correct mathematical notation for the calculation is as follows : (-3)2 , giving the correct answer +9. Use the familiar BODMAS rule.
	I have an FX calculator and am trying to change the mode to comp. I have pressed all the buttons and cannot get comp on the display, why?
	Comp is the default operating mode, and is not displayed on the screen.
	I have just recently purchased a new FX calculator, I am trying to calculate percentages but I am getting the wrong answer, is my calculator faulty? E.g. 100 + 10% = 111.11
	No, the calculator is not faulty. Scientific calculators use Casio percentage logic. To make the calculation, the following keystrokes should be used : 100 x 10% + = 110 Note. If the percentage needs to be subtracted, the subtract key (-) should be pressed instead of the plus key (+)
	I have an FX calculator and am trying to do a simple calculation, and I am getting the wrong answer. E.g. 10 + 2 x 2 = 14, when the answer should be 24, what is wrong?
	The reason for this is, the calculator follows the correct mathematical logic, performing calculations in the following order : Brackets Of Divide Multiplication Addition Subtraction To perform the calculation (10 + 2) x 2 = 24, brackets should be used.
	I had an old FX calculator and used the sin, cos and tan keys, in the new calculator that I have bought I do the same calculation and I get 0 (zero) E.g. 205 ÷ 42 tan = 0. Why is this happening?
	Firstly V.P.A.M stands for, Visually Perfect Algebraic Method, which allows equations to be entered into the calculator as they would be written on the page. This is the reason your calculation is not giving you the right answer. E.g. on paper the calculation would be written as, 205 ÷ tun 42 = 227.68, and this is the way you type it into the calculator.
	What do I press when my screen displays an error message?
	Ac/on key will always clear the message. Note the left \scroll key will take you to the error whenever possible.
