For pixel math from two images, the Merge window. For pixel math on a single image the Formula Window.
The Average window could be used to tune in real time an intermediate result, or for all math of kind:
Result = R1*C + R2*(1-C)
If you have choosen yet an algorithm then I could give a more precise answer.

It's also possible to use the h-alpha as Lum in "LRGB combine" then use the Average window to tune the result.
