thankk you but what is the Gr ? you use it on the final pixelmath, but I don't know how to create it

Is this right? .5*red+.5*blue = Br (blue component) .5*red +.5 * Green = Gr (green component) red-.25*(original blue+green) = RMBG (red component) combine: Red: .75*RMBG+.25*Gr Green:.75*gr+.25*RMBG Blue: Br

I wanted this video to work for me, but you have to understand that I’m a beginner so I don’t know how to do some of the processes work. For example when you are combining the r,g,b pictures in pixel math you don’t explain how to actually add the pictures to pixel math nor do you explain how I would only add 50% of the image. So as much as I wanted this to help me it doesn’t. I doubt any beginner to pixinsight will find this video helpful.
