On a calculator, there is a reciprocal key $1/x$, which can find the reciprocal of the input non-zero number (Note: sometimes you need to press the shift or 2nd key before pressing the $1/x$ key, but this will not be further explained below). For example, if you input 2 and press the $1/x$ key, you will get 0.5. Now, a number is input into the calculator, and the following sequence of keys is pressed: $1/x - 1 = 1/x - 1 =$. The result displayed on the screen is -0.75. What was the original number input?
