How to measure voltage difference between two different nodes in QSpice (i.e.) both nodes being other than ground? One way is math and subtract the voltages. Any other method?

If your question involves viewing the differential waveforms, use the Alt key and the left mouse button to plot circuit net differences in the plot window. While holding down the Alt key, click-n-hold the left mouse button when the cursor is over the first net, then (while holding the left button down) position the cursor over the second net and release the left button. The resultant difference waveform will be presented in the plot window. (if you only meant “measure”, then ignore this response)
