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.

Multiply or Divide
When you select the multiply or divide math function, the Source 1 and 
Source 2 values are multiplied or divided point by point, and the result is 
displayed.
