Use Part expr = {{cb S V/2}}; expr[[1]] {(cb*S*V)/2} expr[[1, 1]] (cb*S*V)/2 Bob Hanlon ---- Obaid Rehman <Obaid.Rehman at student.adfa.edu.au> wrote: ============= Hi , there I am wondering if some one can help me in my issue. After some Algebraic manipulation I get the result but it is inside the two parenthesis e.g. {{........... }}. The problem is that Mathematica understand it as a list or matrix entry. If I need to use this result directly into the matrix manipulation it gives the error. Question is how to get rid these extra parentheses in the result that Mathematica add itself? e.g {{cb S V/ 2}} U can see there is no need of these extra parenthesis Obaid This message is intended for the addressee named and may contain confidential information.
