@anubhavsingh2947 in our course we don't use absorption. This is strictly in line with the conventions used by Symbolic logic by I M Copi not the Introduction to Logic by the same author.
Don't know how are you applying the rules I didn't get these rule in copi as you are using .but I have done pausing the video with scp...but the lengthy process that you have applied is gone over my head ...???
Sir, In which book we can find these type of questions? And in line no. 2, can we apply Material Implication in one go? Or we have to apply it in step-by-step?
Thankyou sir you are a good teacher ❤
10:57 sir I think it should be DeM instead of distribution
sir you could have used absorption at step 5 i would have been lot easier

You can apply MI in one single step as well. This question is from Copi ... just that I modified it.
