How do I do reciprocals on a casio calculator.?

Question

I've forgotten the button and how to do it.

Say i wanted to find the reciprocal of 2/1 how do i do it.

I don't want the answer i know its 1/2 but how do it on the calucator. What sign is it?

Its the Casio fx-991ms but i think most casio calucators r the same.

In skl i think we used the x-1 button

Answer 1

Store the number in the memory with M. Then type 1, press division sign then press RM, then equals.

Answer 2

There are two ways of representing reciprocal depending on the model of the Casio.

My Casio has the "1/x" button:
Press 2/1 followed by "1/x"

For those that don't, there will be the "x^-1" (x to the power of -1) button:
Press 2/1 followed by "x^-1"

If it doesn't have either (which is unlikely), it will have the "x^y" button:
Press 2/1 followed by "x^y" then press "-1"

Answer 3

Either they'll be a button which says '1/x', which you can use, or alternatively you can go to all the effort of pressing the '1' button, and then the divide button instead.

(In case you didn't quite get that: the reciprocal of a number is 1 divided by the number. So just typing 1, divide, number will work.)

Answer 4

You have either a x^-1 button or the button says 1/x. It may be a second function so look hard.

Answer 5

look for the 1/x button

Answer 6

if you have an 'Ans' button just put in 1/Ans. or, if your calculator is like mine, there's a reciprocal button in the top left corner.

Answer 7

take the value an either raise it by ^-1, will will flip the value upside down. or press your value, then press the x^-1 button, if you have one.

Answer 8

i think there's (^-1) or the (1/x) button

Answer 9

Enter your number.
Press the 1/x key.

OR

Enter 1
press /
Enter your number
press =

Answer 10

There should be an "X^-1" button
