Hi everybody, I am a newbie in Mathematica and began programming with it. Could anyone explain this problem to me ? why mathematica can't deal with l={{1,2,3},{2,4,5}} l[[1]][[2]]=3 and here is its error message : Set::"setps": "\!\(l \[LeftDoubleBracket] 1 \[RightDoubleBracket]\) in \ assignment of part is not a symbol." but it can with Part[l,1,2]=3
