Does differencing low pass response from a high pass filter gives a bandpass?

Subtracting one from the other would not produce a bandpass filter. You would have to cascade them in series, so that the output of the first filter was the input to the input to the second filter. This would be the same for analog or discrete filters. The order of which was first would probably not be important.
