The Arduino uno board has 12 availabe digital I/O pins and 6 analog input pins, sometimes, on complex or 'big' projects, we run out of digital pins. Calculate the voltage put onto your analog input by each push button using the known resistance values of your one overall resistor and each individual resistor. The concept used in this example is quite simple. It is important that each of these resistors are different values so that you get different voltages on the analog input, enabling you to identify each button. Connect a jumper wire from pin 2 to the other side of the pushbutton. We assign a different value resistor to each push button so that the analog input will receive a different value (between 0 and 1023) for each button, allowing us to recognise which button has been pressed. Removing a button and resistor shifts the whole divider to a new range of outputs, you need to set these up in your code before it will display the correct button values.
