Description (last modified by )
A minimal case:
sage: (k,n) = var('k,n') sage: sum(abs(-k*k+n),k,1,n) sum(abs(-k^2 + n), k, 1, n) sage: _(n=8) sum(abs(-k^2 + 8), k, 1, 8) sage: _.simplify() sum(abs(k^2 - 8), k, 1, 8)
I would expect _.simplify()
or .expand()
to give me the result 162
but this does not work.
