Here's the Karnaugh map:
The answer I should be getting from the Karnaugh should be:
T = R ∙ (CGM)'
I'm really not seeing how this was arrived at through any simplification methods I've learned thus far. I can see the answers that are intended are correct (I think), though.
From what I know, the best answer I can come up with to simplify (only) the Kargnaugh map is:
T=RCG'+RCM'+RC' to: T=R∙(CG'+CM'+C')
