I'm presuming that the 1/x button in the calculator is the reciprocal function.
If I type 2 1/x = then I get 0.5 ... so far, so good.
Now I want to take the reciprocal of 649/35
I type 649/35 and press = ... and get a number around 18.54
If I now press the reciprocal button, it just appends x1÷ to the number. If I then press = it says "Invalid format used"
If I type 649/35 then 1/x all I get is 649/35x1÷ and nothing happens. If I press = then I get the same "Invalid format used" message.
So is there an easy way to find the reciprocal of a result (of a prior calculation) ?
