20 hours ago comment added Michael E2 @azerbajdzan My recent edit included a link to the Q&A where the issue with Series[] was first noted.
20 hours ago comment added Michael E2 @march Thanks for the edit. I would have done it, but I was having internet issues. Most of the http requests were timing out. I never got to see your answer until after it was deleted.

yesterday comment added Gilbert @march I will say that your code explanation was helpful, being that I am not yet a power user.
yesterday comment added march @azerbajdzan Nah, my post should be deleted because it clutters things up to have two answers that are essentially the same. If OP wants the explanation for the code, I can always edit this post to include the explanation.
yesterday comment added azerbajdzan @march With "the same" I was referring to the same bug of Series in both answers not that the answers were the same. You didn't have to delete your answer because of that.
yesterday comment added march @azerbajdzan I didn't even read MichaelE2's post carefully enough to realize that mine was the same answer, just coded slightly differently. I am deleting my post. But that bug is awful. (I didn't see it because I was using 12.0.0 to do my testing, but I do have 14.3.0 on another computer. Has this bug been reported?)
yesterday comment added azerbajdzan @BobHanlon It seems like a serious bug in Series.
yesterday comment added Bob Hanlon @azerbajdzan - Add and subtract a constant, e.g., (Normal@Series[(A + 1) /. v : Alternatives @@ Variables[A] :> v $t, {$t, 0, 1}] /. $t -> 1) - 1
yesterday comment added azerbajdzan @Gilbert a^4 == Times[a,a,a,a]
yesterday comment added Gilbert @azerbajdzan it's a good question, but I only included Plus and Times within the scope of the question, not Power.
yesterday comment added azerbajdzan Is it a bug in Series or bug in your code, because for A=a^4 it does not seem to produce a correct output. Looks more like a bug in Series though.
yesterday comment added Gilbert Thank you! I suppose my next question on this site should be an explanation of how this works. lol
