RE: Absolute value: sometimes CAS is very clever, sometimes not!

sorry for my bad English

x ≠ -1 should not make a literal comparison x ≠ -1 => 1 synonyms of true, this should leave the symbolic expression, please try the sequence

go to [CAS/settings] Simplify flag: maximum
assume(x,symbol); [enter]
answer:=domain((1/(x+1)),x); returns 1 // the correct output is x ≠ -1
