Trying one of the followings... In[209]:= o = {{0, 1}, {2, 3}, {4, 5}} Apply[Plus[#1^2 + #2] & , o, {1}] (Plus[#1[[1]]^2 + #1[[2]]] & ) /@ o o /. {(x_)?NumberQ, (y_)?NumberQ} -> x^2 + y MapThread[#1^2 + #2 & , Transpose[o]] Out[209]= {{0, 1}, {2, 3}, {4, 5}} Out[210]= {1, 7, 21} Out[211]= {1, 7, 21} Out[212]= {1, 7, 21} Out[213]= {1, 7, 21} Dimitris phoenix7... at gmail.com : > I'm trying to get the following code to work: > > Map[#1^2 + #2 &, {{0, 1}, {2, 3}, {4, 5}}] > > The goal is to use a pure function in order to achieve the result: > {1, 7, 21} > > The issue is that the evaluation involves #1^2 + #2 & [{0,1}] > instead of #1^2 + #2 & [0,1] > > Thanks, in advance.
