I would usually write that as:
(amat = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}}) // MatrixForm
amat[[1]][[1]]
amat[[1, 1]]

Hello there
I am new to Mathematica. In one of my attempts to understand how it works,
I tried the following example
A={{1,2,3},{4,5,6},{7,8,9}} //MatrixForm
The result seems to be a matrix 3x3 but when I try A[[1][1]], the whole
first line shows up instead of just one element. If I don't use MatrixForm,
it works fine. How can I see a matrix in nice format without wrecking
everything?
Many thanks
Ed
