```[This post has been delayed due to email problems - moderator]

hello,

ai have the next code :
a = {{1, 4}, {34, 5}}
b = {{12, 4}, {4, 35}}

and ai want to obtain a matrix like this:
rez={{1+12,4+4},{34+4,5+35}}

..
if i use
c = {{StringForm["a[[1,1]]+b[[1,1]]"], StringForm["a[[1,2]]+b[[1,2]]"]},
{StringForm["a[[2,1]]+b[[2,1]]"],
StringForm["a[[2,2]]+b[[2,2]]"]}}
i obtain :
\!\(\*FormBox[
RowBox[{"(", "\[NoBreak]", GridBox[{
{"\<\"a[[1,1]]+b[[1,1]]\"\>", "\<\"a[[1,2]]+b[[1,2]]\"\>"},
{"\<\"a[[2,1]]+b[[2,1]]\"\>", "\<\"a[[2,2]]+b[[2,2]]\"\>"}
}], "\[NoBreak]", ")"}], TraditionalForm]\)

but ai want the numerical values ..
thank you verry much
