Use Part

expr = {{cb S V/2}};

expr[[1]]

{(cb*S*V)/2}

expr[[1, 1]]

(cb*S*V)/2

=============
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
