Add or Subtract
When you select add or subtract, the Source 1 and Source 2 values are
added or subtracted point by point, and the result is displayed.
You can use subtract to make a differential measurement or to compare
two waveforms.
If your waveforms' DC offsets are larger than the dynamic range of the
oscilloscope's input channels you will need to use a differential probe
instead.

Source 2 values are multiplied or divided point by point, and the result is
displayed.
