Use the (-) key next to the decimal point key to enter the negative sign, not the - key. The (-) key is for negative values, the - key is for subtracting one value from another.

Press numbers display syntax error how solve a problem?


The order in which you are entering numbers and operations is not correct. For example, if you enter 5++2 most calculators will flag this as a syntax error.
On some calculators you calculate square roots as follows: 25 [SQRT]= gives 5. That is the correct syntax for this type of calculators.
For the newer ones you press the SQRT key and see displayed the square root symbol followed by a left parenthesis. You enter the number, close the right parenthesis, then =. If you do not respect the order you get a syntax error.
I cannot say more because I have no idea what you were trying to do, and more importantly, I do not know the make and model of the calculator.

SYNTAX ERROR


I am willing to bet that if the calculator could talk she would tell you to stop feeding it commands that make no sense. Joking aside, each command has a certain syntax, similar to sentences you make in English: a prescribed order of the components of the sentence.

For some calculators (the older generations) you press a number then the square root key to get the square root. For the newer ones, you press the square root key. The calculator keeps waiting until you enter the radicand, then it calculates the root.
So before using the command you must know in what order to press the key sequence. If you get an error with a certain key order, do the opposite.

Now, why is the calculator giving you a syntax error always?. There could be may reasons.Try a simple addition or a multiplication. If you get a syntax error, it may be due the computational mode. You may be in statistics mode , or some other modes, I cannot begin to guess, because you say nothing about what you were doing when you get the errors.
Try to reset the calculator to get to default computational mode.

I dont know how to find the square root on my casio fx-300ES scientific calculator problem it wont let me square root 42 , when i square root 42 , 42 keeps coming and not the answer


To calculate a square root you press the square root key. A radical will be displayed. You type in the positive number whose root you want. Press the EXE key.

I'm doing radicals I need to type an exponent into my calculator that goes before the square root not after. how do i do that (5) as an exponent square root of 32.....the answer is 2 but how do i type it...


Use the xth-root function to compute any root. It's the fifth entry on the MATH menu, which you can get by pressing the MATH key. The fourth entry on the same menu gives you the third root without needing the 3 to be specified.

For example, to compute the 5th root of 32, press 5 MATH 5 3 2 ENTER.

It wont give the answer to the square root of 76 :S


Maybe your syntax is incorrect. But more likely, it gives the right answer but you do not recognize.
Look on the narrow indicator band on top of the screen. If there is a Math indicator you are in MthIO (textbook display). In this mode results are in the form of radicals
SQRT(76) =2*SQRT(19) Here SQRT represents the radical (square root symbol).

If there is no Math indicator, your calculator is in LineIO and all results are in decimal form so that SQRT(76) =8.717797887

To set MthIO press [SHIFT][MODE][1:MthIO]
To set LineIO press [SHIFT][MODE][2:LineIO]
To toggle between radicals/fractions to decimal press [S<=>D] key above the [DEL] key.

I think you are using the minus symbol instead of the negative symbol (located below the 3).

Poisson


Hello
To raise a number to any power you use the [^] caret key or on some calculators the [x^y] (x raised to exponent y)

20^(4) =160000

20 to the power of negative 3
20[^] 3 [(-) or +/-] ENTER gives 1.25x10^(-4) = 0.000125 (-) is the small minus sign.

If that gives you a syntax error
20[^] [(-) or +/-] 3[ENTER] = 0.000125

27 [^] (1/3] represents the cube root of 27 which is 3.
Hope it helps.
