Hi all
I was looking on the issue https://github.com/sympy/sympy/issues/8531
though i disagree for that simplification to occur.
>>> n = Symbol('n', integer=True, positiv=True)
>>> factrial(n)*(n+1) # i think this should not be simplified to
factorial(n+1)
factorial(n)*(n+1) # currently happens, which i think is correct.
>>> n = Symbol('n', integer=True, positiv=True)
>>> ( factorial(n)*(n+1) ).rewrite(factorial)
factorial(n)*(n + 1) # why not returned as factorial(n + 1) ??
I was thinking if there is currently any way of rewriting it as
`factorial(n + 1)`
