I have the following as the output of a calculation
a.b+(-a).b
and I would like Mathematica to evaluate this to zero. Is there a way to specify that for my purposes (-a).b is the same as -(a.b)?
(I’ve been searching for a solution and tried a number of things but thought it would be better to keep my question clear and concise not to distract with irrelevant descriptions of my attempts solving it.)
