I observed the following weird behavior of the symbolic engine. sage: x/x 1 sage: x^2/x x sage: (x^2+x)/x (x^2 + x)/x sage: assume(x>0) sage: assume(x,'real') sage: assumptions() [x > 0, x is real] sage: (x^2+x)/x (x^2 + x)/x
To clarify: first, I consider the first two simplifications slightly incorrect (x/x is undefined if x=0, or possibly if x is in some weird algebraic structure). However, if x/x==1 and x^2/x==x then I wonder why simplification of (x^2+x)/x is not done? In this case, .simplify() does not help, .full_simplify() does. In my original example though, .full_simplify() did something crazy, so I was led to this. In general, is there some explanation regarding which simplifications one can expect to be done automatically and which by the two simplify-functions?
