Hello everybody! I have a problem in using the Mathematica Package which is probably a bit stupid but very annoying when you have long expressions.. When I "FullSimplify" big equations, in the output the negative sign is always put aside i.e. if I do something like: FullSimplify[(1-s)(1-a)] I obtain (-1+s)(-1+a). Which is very confusing with long and tedius expressions. Does anybody know a way to solve this problem? Thanks a lot for your help!!
